In 2000, the last year of the 20^th century, a book came hot off the press (yes, at that time most dictionaries were still made of paper), the Dictionary of Doubts and Difficulties in English-Spanish Medical Translation, and it quickly became the top terminological book for medical translators working into Spanish. Five years later in 2005, the second edition of the dictionary came out in a revised, improved and much expanded version, now with a pan-Hispanic perspective, but still in hard copy only.

I had to wait for eight more years–and within that time for none other than the ground-breaking Dictionary of Medical Terms (2011) from the Royal Academy of Medicine in Spain–to produce the Libro rojo and take the leap from paper to cyberspace. The third edition of the dictionary, and first on the Cosnautas website, had a new name: Dictionary of Doubts and Difficulties in English-Spanish Medical Translation (2013), now only in electronic version for online research.

Since then, I have updated the work every six months, and thus over these nine years, 18 updates have marked the progressive improvement and expansion of the Libro rojo. But only now, with the deadly Covid-19 pandemic about to pass into history, have I decided to publish, at last, a fourth edition of the dictionary. The newly revised Dictionary of Doubts and Difficulties in English-Spanish Medical Translation (2022) will provide the basis and the model for a version in Portuguese already being prepared by the Brazilian doctor and translator Carla Vorsatz, and we hope to release it on the Cosnautas platform in its preliminary version this year.

The internal structure of the work has hardly changed in all this time. The lexicographical structure of the dictionary continues to be essentially identical to that of the first edition in hard copy, which as I mentioned above was originally published in 2000. There is also no substantial change with respect to the Cosnautas edition from 2013 mentioned in the prologue to the third edition.

 So, what has changed since the third edition of the dictionary (version 3.01, July 2013) in this new fourth edition (version 4.01, March 2022)?

Mainly, it is the magnitude of the work. Libro rojo has gone from 47,344 terms in version 3.01 to 60,757 entries in version 4.01. In other words, almost 13,500 new entries corresponding to neologisms, technisms and expressions that are misleading or difficult to translate from nearly every biomedical field and other areas of knowledge. History rolls on, with medical breakthroughs taking place non-stop: the continuous discovery of new monoclonal antibodies, Obama's healthcare reform, the publication of the 23rd edition (2014) of the Dictionary of the Royal Spanish Academy and its 23.1 (December 2017), 23.2 (December 2018), 23.3 (November 2019), 23.4 (November 2020), and 23.5 (December 2021) updates, robotic surgery and telemedicine, new chemical elements approved by IUPAC in 2016, the revolutionary CRISPR technique and Brexit for those of us in Spain in January 2020, the first coronaviruses, the Zika virus, the pandemic of Covid-19 and the new ARNm vaccines–all these things have left their mark on the Libro rojo. For those who are curious to know the type of terms that were added to the dictionary and when exactly, you will see in table 1 a list of 600 new entries in the Libro rojo between January 2015 and March 2022. It is only a small selection of the 13,000 new entries in the fourth edition, but it may help to show the overall vision of the work.

Have you ever wondered how new terms get into the Libro rojo? Where did the 13,000 new entries of the fourth edition come from? Many of them arose from my own doubts. I have been working in medical translation for 35 years, and I rarely spend a day without translating or reading a medical text in English. It is also quite rare for me to spend a day without encountering some uncertainty or difficulty in translation, and when it happens, I always try–regardless of my deadline–to find the time to document it and add it to the Libro rojo. I am now an expert in uncertainties and difficulties in translation, though this is not to say I am an expert in resolving them! I am only an expert in having doubts.

As with the second and third editions of my dictionary, I also continue to collect knowledge from out in cyberspace where my fellow translator colleagues go with their queries: the MedTrad and Tremédica discussion threads, of course, but also–for this fourth edition–the main social media channels (Facebook, LinkedIn and, above all, Twitter).

Apart from this, I would like to highlight two other abundant resources that my dictionary, and mine alone, benefits from. They are two places of query that would have delighted the lexicographers of previous generations. Ever since the Libro rojo was published in Cosnautas, the interactive and collaborative model of Cos has allowed me to tap into the enquiring minds of the cosnauts themselves on a daily basis. In the nine years in which the third, now extinct, edition of Libro rojo (versions 3.01 to 3.18, July 2013 to February 2022) was active, more than 300 cosnauts contributed on several occasions with ideas for improvement: some who wrote me simply to correct a small errata (always an important task, to rid the text of "rats"); others, essentially, who wrote to propose an interesting new entry I probably would not have encountered on my own.  In table 2 you will see a hundred additions that reached me this way with the name of the cosnaut who threw me down the lexicographical gauntlet. There were several hundred more just like them.

Even more wonderful still, though unforeseen, was another resource that I only discovered once my dictionary appeared on Cos. All users of Cosnautas, merely by consulting the Libro rojo, were already actively collaborating in the process of revision and improvement of the work. I was able to know, with just a few clicks, the most consulted entries in the dictionary, but also–and even more interestingly–which unsuccessful searches were most frequent. If many medical translation professionals are all looking for a term that does not appear in a dictionary of doubts like mine, it must be a recurring problem that perhaps would have to be addressed in the Libro rojo, though it had not been apparent it to me. A meticulous review of the list of unsuccessful searches in each version of the dictionary allowed me to open up the work to a multitude of interesting terms that until then had been ignored, including blueprint, drusen, fibroscan, MedDRA, narrative, ookinete, orthotist and VEGF. Hundreds of the most frequent searches typed in by cosnauts that had once come up empty now show results in this fourth edition.  Table 3 shows more than 300, but in fact there were many more. Among them, there are terms that at a certain point became trendy; during the 2020-2022 pandemic, for example, many of us spent the two years translating texts on epidemiology, the coronavirus, preventative measures, covid vaccines and new antiviral medications. The Libro rojo was enriched by the questions that emerged in my translations and reading, and with others that arose during the compilation of the English-Spanish Covid-19 Glossary  for Cosnautas and Tremédica. But until I reviewed the list of unsuccessful searches from version 3.15 (1 March to 31 August 2020) I did not realize that I had ignored queries as common as CPAP, ECMO, facemask, lockdown, paucisymptomatic, PPE and sanitisation. In this last case, by the way, the Libro rojo actually contained the entry to sanitise, but hundreds of cosnauts did not arrive at it when typing in sanitisation. Many of the queries that produce unsuccessful searches were in fact are due to simple variants (such is the case, for example, in words like hayfever, lightheaded, stenting and tophi, which were unfruitful even though they were listed in the dictionary as hay fever, lightheadedness, stent and tophus), or even frequent errata or incorrect variants (in the dictionary we had balloon and proprietary, but hundreds of cosnauts did not find them when typing ballon or baloon in the first case, and propietary in the second). Unbeknownst to the cosnauts making these failed searches, all their actions were extremely useful to me in improving my work.

The combination of electronic lexicography with the participative model of Cosnautas has been key to achieving both the quantitative and qualitative jump between the third and fourth editions of the Libro rojo. It is thus closer than ever to reaching its goal of becoming the best bilingual dictionary in history.

There is no doubt that in the world of general and specialised dictionaries, translators are spoilt for choice. Considering the sheer number of monolingual, bilingual and multilingual dictionaries, I am sure that many readers will be surprised and somewhat sceptical about the publication of this Diccionario crítico de dudas inglés-español de medicina^†:

“What? Not another dictionary! And what a weird title!“

In the course of this introduction, I hope to convince you that a dictionary of this nature is not only necessary - I can almost hear the critics saying “it fills a gap in the bibliography” - but also that it simply has to have this title. However strange and exotic it initially sounds, the title is certainly not the result of a rash decision or fleeting fancy. Let us dissect the title, word by word.

 * This Introduction is a literal copy of the original version published in the first edition, with some very minor changes to adapt to the new typography and format of the third edition.

^† This was the title for the first two editions (Madrid: McGraw·Hill-Interamericana, 2000 and 2005); for this electronic Cosnautas edition (2013), I decided to rename it Diccionario de dudas y dificultades de traducción del inglés médico, which is the title I will use from now on in this introduction.

In Spanish, unlike in English, grammatical gender is a vital syntactic function that expresses agreement among nouns, adjectives, some pronouns, articles and certain participles used as adjectives. Grammatical gender poses major challenges for lexicographers, particularly with regard to nouns that name persons.

      In a bilingual dictionary, it is fairly easy to denote the grammatical gender of inanimate nouns, since most objects have a single form and explicit gender: biopsia, for example, is always feminine; quirófano is always masculine. In a bilingual dictionary, it is therefore easy to state that "biopsy is biopsia" and "operation room is quirófano".

      However, in the case of nouns that name persons, most have a double gender form in Spanish (e.g., el cardiólogo and la cardióloga, el bioquímico and la bioquímica) or they are invariant with an implicit gender (e.g., el dentista and la dentista, el psiquiatra and la psiquiatra). Very few nouns that are invariant with explicit gender can be used for both biological sexes without changing the grammatical gender. This is true of masculine (e.g., bebé, cadáver, personaje, ser) and feminine nouns alike (e.g., criatura, familia, gente, persona, víctima).

      Nouns naming persons that undergo gender-related changes are a major problem for bilingual dictionaries. Some dictionaries opt to use an inclusive masculine form. This strategy is very common in general spoken language when referring to a person whose sex is not yet known (e.g., "espero que en este hospital haya un ginecólogo de guardia"). These dictionaries state, for example, that "neurologist is neurólogo", running the risk that their strategy may be misinterpreted as gender bias against women. Other dictionaries, on the other hand, prefer to expand the double forms and state that "neurologist is neurólogo o neuróloga" or they opt for a double abbreviated form, "neurologist is neurólogo/-ga".

      These two alternatives for solving Spanish gender variance work quite well in monolingual dictionaries (where they are used as isolated headwords) and in simple bilingual dictionaries (where direct equivalents are usually given in the form of one- or two-word entries). However, in complex bilingual dictionaries that provide a range of compound expressions, these strategies become cumbersome and confusing. For example, a good surgeon becomes un buen cirujano, una buena cirujana (not to mention un/a buen/a cirujano/­na!). Even more long-winded and convoluted are explanatory sentences with nouns, adjectives and articles that all express gender agreement. A sentence such as "Además del médico adjunto y el auxiliar administrativo, solamente pueden estar presentes el paciente ingresado y un amigo íntimo o un familiar cercano" should reflect all its variants: "Además de la médica adjunta y el auxiliar administrativo, solamente pueden estar presentes la paciente ingresada y un amigo íntimo o una familiar cercana", "Además del médico adjunto y la auxiliar administrativa, solamente pueden estar presentes el paciente ingresado y una amiga íntima o un familiar cercano", "Además de la médica adjunta y la auxiliar administrativa, solamente pueden estar presentes la paciente ingresada y un amigo o amiga íntimos o una familiar cercana" and scores of other possibilities that the Spanish language contemplates. Instead of increasing the reader's understanding, these strategies actually further confuse the issue. Worse still would be a double expanded option ("Además del médico adjunto o la médica adjunta y el auxiliar administrativo o la auxiliar administrativa, solamente pueden estar presentes el paciente ingresado o la paciente ingresada y un amigo íntimo o una amiga íntima o un familiar cercano o una familiar cercana") or a double abbreviated option ("Además del/de la médico/­ca adjunto/­ta y el/la auxiliar administrativo/-va, solamente pueden estar presentes el/la paciente ingresado/-da y un/a amigo/-ga íntimo/-ma o un/a familiar cercano/-na").

      The options for nouns that name persons also apply to all English adjectives for persons and things, but with an even greater degree of complexity. This is because adjectives have gender and number in Spanish, but not in English. An adjective such as white, for example, would be blanca in white skirt (falda blanca), but blancos in white trousers (pantalones blancos). So, in an exhaustive bilingual dictionary, it would no longer suffice to say that white means blanco, as is usually the case, but white means blanco, blanca, blancos or blancas or, in the abbreviated form, white means blanco(s)/-ca(s). Again, this is extremely cumbersome and confusing, which is just what a dictionary seeks to avoid.

      Therefore, the time-old practice in the history of lexicography is to tend towards simplicity and clarity over exhaustiveness. Everyone who regularly uses a monolingual dictionary will know, for example, that bisturíes has to be searched for as bisturí, because it does not have its own entry. Likewise, soy, eras, fue, seremos and serían have to be searched for as ser; librito as libro; dificilísimo as difícil, and so on and so forth.

      I have never heard anyone suggest that searching for different verb forms using the infinitive shows bias against past, present, future or imperative conjugations. And no one contends that finding Spanish plurals only by searching for singulars implies a number bias that might empower the individualistic nature of our modern capitalist society against the plurality and sense of community that is defended by the social revolution of Christianity or anarchy. Everyone readily understands that these are mere conventions of usage, designed to simplify dictionary searches, with an eminently practical purpose. So it should not be hard to interpret grammatical gender conventions the same way, as simple grammatical conventions designed for practicality.

      In the Dictionary of doubts and difficulties in English medical translation, I have sought to avoid the long-windedness of expanding each and every Spanish grammatical gender variant of an English term or phrase. I have therefore opted to apply the following conventions:

1. For headwords and compound expressions (denoted by the symbol ●), and in the main body of the articles, I have given the Spanish equivalent in an inclusive or generic single gender form. In line with general Spanish usage, the inclusive gender is usually masculine, except for a few cases in which the inclusive feminine form is used in general speech to represent both grammatical genders. Therefore, the equivalent terms rheumatologist (reumatólogo) and obstetric nurse (comadrona), should be interpreted in the standard, underlying sense of rheumatologist (reumatólogo or reumatóloga, depending on the context) and obstetric nurse (comadrona or comadrón, depending on the context), respectively.

2. In the case of example sentences (denoted by the symbol ◘), however, I have used the inclusive masculine form only (or, more rarely, the inclusive feminine form) when the example refers to a group of men and women or a person of indeterminate or unknown sex. In all other cases, I have tried to alternate examples in which an English noun has a standard, underlying Spanish masculine equivalent with others that have a feminine one, so that the reader is constantly aware that the transformation from English to Spanish involves an inherent grammatical gender decision. Therefore, with words such as child and doctor, the reader will encounter example sentences such as My child is badly injured (mi hijo está gravemente herido) and The doctor ordered complete rest (la médica le prescribió reposo absoluto) together with other examples such as She was often ill as a child (de pequeña se ponía enferma con frecuencia) and The doctor put the patient out for surgery (el médico anestesió a la paciente para la intervención quirúrgica).

      Notwithstanding the above, for some entries where I feel it would be useful for the reader to have access to more detailed comments, I have discussed specific problems encountered when translating English - a language with almost no traces of grammatical gender - to Spanish, where this feature is ever present. Take, for example, the first comments on usage (denoted by the symbol ►►) in the entry for Dr. or the comment on meaning usage (denoted by the symbol ►) in meaning one, sub-meaning a), in the entry for nurse.

To Lydia, Antonio, Álvaro, Isabel and Miguel.

Many of the hours that I spent compiling this dictionary

- and I can assure you there were many indeed - were in fact theirs.

Many friends and translators have sent in suggestions and comments to improve the dictionary, and have helped solve terminology doubts in person, by phone, post and e-mail. In this respect, the following colleagues have made the biggest or most assiduous contributions to this third edition of my dictionary of doubts: José Rafael Blengio Pinto (Querétaro), Guido Castañeda Macchiavello (Barcelona), M. Gonzalo Claros Díaz (Malaga), Fernando Contreras Blanco (Madrid), Xavier Fuentes Arderiu (Barcelona), Betty Galiano (Rosario), Carlos Gancedo (Madrid), Isabel García Acha (Salamanca), Carlos Garrido (Vigo), Javier Hellín (Madrid), Antonio Hernández Rolón (Mexico), José María Izquierdo (Cordova), Pablo Mugüerza (Valladolid), Laura Munoa (Madrid), Ignacio Navascués(Madrid), Emilia Picazo (Mexico), Rafael Rivera (Miami), Julio Rodríguez-Villanueva García (Soto del Real), Gustavo A. Silva (Washington and Geneva), Sandro Tomasi (New York), Manuel Talens (Valencia), Damián Vázquez (Buenos Aires and Washington) and Elisa Vilaret (Barcelona), as well as, in particular, Guillermo Murillo Godínez (Querétaro) and, especially, Juan Manuel Martín Arias (Madrid)[*].

My colleagues, numbering almost three hundred, on the mailing list servers MedTrad <www.rediris.es/list/info/medtrad.html> (since September 1999) and Tremédica <tremedica.org> (since February 2008) have been extremely helpful. This treasure trove - over one hundred thousand archived messages of which I am proud to say I have read each and every one - has been without doubt my most valuable source of information over these long years of work, fine tuning this third edition of the dictionary of doubts. In fact, in my opinion, the MedTrad and Tremédica lists have been so valuable that they should be acknowledged as the collective co-authors of this reference work. I exaggerate not.

Since launching the third edition of the Libro rojo on Cosnautas, I have received proposals for additions and corrections from many colleagues. Their suggestions have greatly improved this fourth edition, and I would like to publicly thank the following cosnauts for their contributions:
