4. PREFACIO
Cuando los originales del Engineers’ Dictionary quedaron listos en 1943, la
segunda guerra mundial estaba en su apogeo y esto llevó a la casa editora y al
autor a convenir de que el libro no debía exceder de unas cuatrocientas cincuenta
páginas. Algún material debió ser retirado y aunque el libro resultante trataba
detenidamente de ingeniería civil, no pudo contener muchos términos usados en
otras ramas de la ingeniería.
Poco tiempo después de su publicación yo me retiré del trabajo activo de
ingeniería y desde entonces he tenido amplias oportunidades para dedicarme a la
compilación de un diccionario más extenso. El material que debió ser retirado
se ha agregado ahora y se ha estudiado una gran cantidad de material nuevo.
He consultado con muchos amigos de la América Latina y en cada viaje he traído
conmigo publicaciones técnicas de diversas clases como fuente de términos
españoles. Constantemente he escudriñado las revistas de ingeniería y los
libros nuevos publicados en ambos idiomas.
El campo de acción sigue siendo la ingeniería y las referencias frecuentes a la
química, la geología o la metalurgia no significan que estas materias estén total­
mente abarcadas en este libro. Cada una de ellas necesitaría un volumen aparte.
Los términos incluidos de estas u otras materias son aquellos regularmente
requeridos en un trabajo o estudio de ingeniería. Igual criterio se ha seguido en
la selección de algunos pocos términos de finanzas, seguros y transportes.
Al ampliar la obra mis principales propósitos han sido los siguientes:
Abarcar la ingeniería eléctrica y mecánica en manera mucho más amplia.
La radio que no se mencionó para nada en la primera edición ha recibido cuida­
doso estudio. Se han incluido términos importantes de la televisión.
Poner al día todos los ramos de la ingeniería civil. Se ha dado especial atención
a la mecánica de los suelos, a la fotogrametría y al proyecto y construcción de
aeropuertos.
Incluir los términos más importantes correspondientes a minería, arquitectura
naval, explotación forestal, industria azucarera y campos petrolíferos.
Una nueva adición es la indicación de género de los substantivos en español.
El objeto de un diccionario técnico es proporcionar información que no se
encuentra en otra parte. Se supone que el diccionario de Webster incluye todas
y cada una de las palabras del idioma inglés, aún las más técnicas, pero no abarca
las frases que figuran en glosarios oficiales de las sociedades de ingeniería.
Muchas de las palabras de este libro se encuentran también en los mejores
diccionarios generales inglés-español. Buttress se encuentra en cualquiera de
ellos, igualmente que thread, pero no buttress thread. Aguja y también infernal
se encuentran, pero no aguja infernal. La mayoría de mis esfuerzos se han

concentrado en el registro dé significados o equivalentes de locuciones que no
pueden expresarse con una sola palabra.
La nomenclatura de piezas de maquinaria requiere un constante uso de buen
criterio. Cada fabricante tiene su propia lista de piezas para cada máquina
y algunas máquinas constan de tantas que llegan al millar. Las partes principales
de una máquina deben enumerarse y con ellas, fuera de los términos como
cojinete, leva, tornillo, resorte, rodillo y válvula, deben identificarse con un
nombre la gran mayoría de las piezas componentes.
A pesar de algunos consejos adversos recibidos, yo creo todavía que las
definiciones están fuera de lugar en un diccionario técnico bilingüe. El interesado
que busca en un libro como éste el término slvp-ring motor quiere encontrar el
equivalente aceptado en español y no una descripción del motor. Las de­
finiciones aumentarían mucho el volumen del libro. La práctica seguida ha
sido la de definir un término solamente al carecer de un equivalente satisfactorio
y en algunos casos para evitar ambigüedades.
Es obvio que existen en este libro muchas palabras, tanto en español como
en inglés, que tienen otros significados además de los anotados. Se han omitido
los significados no técnicos, así como aquellos que pertenecen a la botánica,
zoología y otras ciencias de interés muy relativo para el ingeniero.
Algunos de los términos de la obra original han sido criticados llamándolos
“ mal español” . Un crítico me ha dicho que la incorporación de tales términos
a un diccionario tiende a perpetuarlos y a perjudicar el idioma. M i punto de
vista es que la exactitud de los términos técnicos en cualquier idioma es esta­
blecida por los técnicos que los crean y los usan, y la tarea del compilador del
diccionario es la de registrar su uso. En esta obra se trata de dar a los técnicos
de habla inglesa de la América del Norte la terminología de ingeniería usada en
los países de habla española de América y viceversa. Términos tomados de
publicaciones oficiales, de especificaciones de ingenieros y de libros de texto se
consideran expresiones usadas y “ aceptadas” . Para muchos miles de términos
en inglés no hay equivalente en “ buen español” si se sigue el criterio de la Real
Academia. Esta es la razón de la diferencia entre unos 125,000 términos en
el diccionario de la Academia y de unos 500,000 en el de Webster.
Los equivalentes en español de marcas de fábrica o de comercio en inglés
presentan un problema. La simple aseveración de que estos nombres no pueden
traducirse no soluciona el problema, porque muchas traducciones son de uso
corriente en los países de habla española. Muchos de estos términos ya se han
incorporado a otros diccionarios en español o en español-inglés. Hay propietarios
de marcas de fábrica o comercio quienes han creado expresamente equivalentes
en español P»ra usarlos en su propaganda. Y o he seguido la práctica de incluir
todo término de esta clase que he encontrado en buen uso técnico. Debe notarse
que muchos términos en-inglés de esta clase se han hecho tan conocidos que con
la sanción de Webster regularmente se escriben sin mayúscula.' Para la mayoría
de estos términos hay equivalentes en español igualmente bien establecidos.
Muchos amigos que me proporcionaron consejos en la preparación de la
obra original me han ayudado de nuevo. Estoy particularmente agradecido al
señor George C. Bunker con quien he pasado muchas horas en Caracas. Además
de concederme amplio tiempo, me presentó a ingenieros venezolanos de quienes
obtuve material de gran valor. Para muchos términos de ingeniería sanitaria.

8. PREFACE
Under the war conditions of 1943, when the original Engineers’ Dictionary
was in preparation, publisher and author agreed that the book ought to be kept
down to about 450 pages. Some material had to be laid aside, and although the
resulting book dealt thoroughly with civil engineering, it could not go very far
with the terms of other fields.
Shortly after publication of the original book I retired from active work and
have since found ample time to devote to the compilation of a much more com­
prehensive dictionary. The items formerly laid aside have been worked in and
a mass of new material has been studied. I have consulted many friends in
Latin America and from each trip have brought back technical publications of
many kinds to be worked over for my Spanish terms. I have constantly combed
the engineering periodicals and the newest books in both languages.
M y field is still engineering. Frequent references to chemistry, geology, or
metallurgy do not mean that these subjects are covered. Each of them would
need a volume of its own. Terms of these and other sciences here included are
those which are regularly npeded in connection with engineering work. The
same criterion has governed the selection of a very few of the terms of finance,
insurance, and transportation.
In enlarging the book my principal objectives have been three:
1. T o cover electrical and mechanical engineering much more thoroughly.
Radio, of which the first edition had nothing, has been given thorough study.
Important terms of television have been included.
2. T o bring all branches of civil engineering up to date. Special attention
has been given to photogrammetry, soil mechanics, and airport construction.
3. T o include the important terms peculiar to mining, shipbuilding, logging,
sugar milling, and oil-field operations.
A new feature is the notation of gender with all Spanish nouns.
The purpose of a technical dictionary is to furnish information not found
elsewhere. Webster’s is supposed to include every word in the English language
no matter how technical, but it does not cover the phrases that are listed in
official glossaries of the engineering societies. M any of the words in this book
will be found also in the best English-Spanish general dictionaries. Broad is
found anywhere and so is irrigation, but not broad irrigation. Buttress is found
and so is thread, but they cannot be combined into an equivalent for buttress
thread. M ost of my effort has gone into pinning down the phrases.
The listing of machine parts calls for the constant use of judgment. Every
manufacturer has his own list of parts for each machine, and some machines
have parts running into the thousands. The principal members of a machine
xi

9. xii PREFACE
must be listed, and 'tfith these, plus terms like bearing, cam, bolt, spring, roller,
and valve, equivalents of the vast riiajority of part names may be written easily.
In spite of some advice to the contrary I still believe that definitions are out
of place in a two-language technical dictionary. The user who turns to slip-
ring motor in a book such as this wants the accepted Spanish equivalents of that
term and is not looking for a description of a slip-ring motor. Definitions would
add greatly to the book’s bulk. M y practice has been to define a term only in
default of a satisfactory equivalent or occasionally to avoid ambiguity.
Obviously there are many words here, both Spanish and English, that have
meanings other than those given. Nontechnical meanings have usually been
ignored, as have those which belong to botany, zoology, or other sciences that,
do not concern the engineer.
Some of the terms in the original book have been criticized as “ bad Spanish.”
One critic tells me that the listing of such terms in any dictionary tends to
perpetuate them and does an injury to the language. M y own view is that
the correctness of technical terms in any language is established by the technical
men who create them and use them, and the job of the dictionary maker is to
record this usage, This book aims to give the North American technical man
the accepted engineering terminology of Spanish America, and vice versa.
Terms taken from official publications, from engineers’ specifications, and from
textbooks are “ accepted” terms. For many thousands of English technical
terms there are no “ good Spanish1 equivalents, if the Royal Academy is to be
’
the criterion. This is the principal reason for the difference between some
125,000 entries in the Academy dictionary and 500,000 in Webster’s.
Spanish equivalents of English trade names are a problem. The simple
statement that proprietary names cannot be translated does not cover the situa­
tion because they are regularly being translated in Spanish-speaking countries.
M ány such terms have already appeared in other dictionaries, both straight
Spanish and English-Spanish. There are owners of English trade names who
have deliberately created Spanish equivalents for use in their advertising.
M y rule has been to include every term of this kind that I have found in good
technical use. It is to be noted also that there are a great many trade names in
English that have become so well known that, with Webster’s approval, they
are regularly written without the capital letter. For most of the terms in this
class there are Spanish equivalents equally well established.
M any friends who advised with me in the preparation of the original book
have again been helpful. I am particularly grateful to Mr. George C. Bunker
with whom I have spent many hours in Caracas. Besides giving freely of his
own time he introduced me to Venezuelan engineers from whom I obtained
material of great value. For terms of sanitary engineering, both in English and
in Spanish, I have to thank Mr. Edmund B. Besselievre of the Dorr Co. and
M r. Tomás R . Yglesias of Mexico City. Señor Juan de Dios Tejada of Havana
gave me his expert advice on many questions. The vocabulary of geophysical
exploration, both English and Spanish, was furnished by engineers of the Socony
Vacuum Oil Co.
