PREFACIOCuando los originales del Engineers' Dictionay quedaron listos en 1943, la segunda guerra mundial estaba en su apogeo y esto llev a la casa editora y al autor a convenir de que el libro no deba exceder de unas cuatrocientas cincuenta pginas. Algin material debi ser retirado y aunque el libro resultante trataba detenidamente de ingeniera civil, no pudo contener niuchos tr~ninos usados en otras ramas (le la ingeniera. Poco tiempo c1espu6s de su publicacin yo me retir del trabajo activo de ingeniera y desde entonces he tenido amplias oportunidades para dedicarme a la compilacin de un diccionario ms extenso. El m:~teri:tlque debi ser retirado se ha agreg:ttlo ahora y se ha estudiado una gran cantidad de rilaterial nuevo. He consultado con muchos amigos de la Amrica Latina y en cada viaje he trado conmigo publicaciones tcnicas de diversas clases como fuente de trminos espaoles. Constantemente he escudriado las revistas de ingeniera y los libros nuevos publicados en ambos idiomas. E l campo de accin sigue siendo la ingeniera y las referencias frecuentes a la qumica, la geologa o la metalurgia no significan que estas materias estn totalniente abarcadas en este libro. Cada una de ellas necesitara un volumen aparte. Los trminos incluidos de estas u otras materias son aquellos regularmente requeridos en un trabajo o estudio de ingeniera. Igual criterio se ha seguido en la seleccin de algunos pocos trminos de finanzas, seguros y transportes. Al ampliar la obra mis principales propsitos han sido los siguientes: Abarcar la ingeniera elctrica y mecnica en manera mucho ms amplia. La radio que no se mencion para nada en la primera edicin ha recibido cuidadoso estudio. Se han incluido trminos importantes de la televisin. Poner al da todos los ramos de la ingeniera civil. Se ha dado especial atencin a la mecnica de los suelos, a la fotogrametra y al proyecto y construccin de aeropuertos. Incluir los trminos ms importantes correspondientes a minera, arquitectura naval, explotacin forestal, industria azucarera y campos petrolferos. Una nueva adicin es la indicacicin de gnero de los substantivos en espaol. E l objeto de un diccionario tcnico es proporcionar informacin que no se encuentra en otra parte. Se supone que el diccionario de Webster incluye todas y cada una de las pa1:ibras del itlioiiia ingls, an las ms tcnicas, pero no abarca las frases que figur:in rn glosarios ofici:iles de las socied:ttles (fe ingeniera. Muchas de las palabras (le esce libro se encuentran taiii1,in en los mejores diccionarios generales ingls-espaol.

PREFACIO

concentrado en el registro de 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 mquina y algunas mquinas constan de tantas que llegan al millar. Las partes principales de una mquina deben enumerarse y con ellas, fuera de los trminos como cojinete, leva, tornillo, resorte, rodillo y vlvula, deben identificarse con un nombre la gran mayora de las piezas componentes. A pesar de algunos consejos adversos recibidos, yo creo todava que las definiciones estlln fuera de lugar en un diccionario tcnico bilingiie. El interesado que busca en un libro como ste el trmino slip-ring motor quiere encontrar el equivalente aceptado en espaol y no tina descripcin del motor. Las definiciones aumentaran mucho el volumen del libro. La prBctica seguida ha sido la de definir un trmino solamente al carecer de un equivalente satisfactorio y en algunos casos para evitar ambiguedades. Es obvio que existen en este libro muchas palabras, tanto en espaol conio en ingls, que tienen otros significados adems de los anotados. Se han onlitido los significados no tcnicos, as como aquellos que pertenecen a la botnica, zoologa y otras ciencias de inters muy relativo para el ingeniero. Algunos de los trminos de la obra original han sido criticados llamndolos "mal espaol". Un crtico me ha dicho que la incorporacin de tales terminos a un diccionario tiende a perpetuarlos y a perjudicar el idioma. bli punto de vista es que la exactitud de los trminos tcnicos en cualquier idioma es establecida por los tcnicos 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 tcnicos de habla inglesa de la Amrica del Norte la terminologa de ingeniera usada en los pases de habla espaola de Amrica y viceversa. Trminos tomados de publicaciones oficiales, de especificaciones de ingenieros y de libros de texto se consideran expresiones usadas y "aceptadas". I'ara muchos miles de trminos en ingls no hay equibalente en "buen espaol" si se sigue el criterio de la Real Academia. Esta es la razn de la diferencia entre unos 125,000 trminos en el d4ccionario de la Academia y de unos 500,000 en el de Webster. Los equivalentes en espaol de marcas de fbrica o de comercio en ingls presentan un problema. La simple aseveracin de que estos nombres no pueden traducirse no soluciona el problema, porque muchas traducciones son de uso corriente en los pases de habla espaol:^. Muchos de estos trminos ya se han incorporado a otros diccionarios en espaol o en espaol-ingls. Hay propietarios de marcas de fbrica o comercio quienes han creado expresamente equivalentes en espao[ para usarlos en su propaganda. Yo he seguido la prctica de incluir todo trmino de esta clase que he encontrado en buen uso tcnico. Debe notarse que muchos trminos en ingls de esta clase se han hecho tan conocidos que con la sancin de Webster regularmente se escriben sin may6scula. Para I:t niayora de estos trminos hay equivalentes en espaol igualmente bien establecidos. Muchos amigos que me proporcionaron consejos en la preparacin de la obra original me han ayudado de nuevo. Estoy particularmente agradecido al seor George C. Bunker con quien he pasado much:is horas en Caracas. Adenls de concederme amplio tiempo, me present a ingenieros venezolanos de quienes trniinos de ingeniera sanitaria, obtuve niateriiil de gran valor. Para n~uchos

tanto en ingles corno r n espaol, tengo qiie agradecer al seor Edmilnd B. Bcsselievre de 1 : ~Dorr ConiI>:lny y al seor Tonibs 11. Tglesins de la ciudad de Itlsico.

PREFACEUnder the war conditions of 1943, when the original Engineas' 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 1 retired from active work and have since found ample time to devote to the compilation of a much more comprehensive dictionary. The items formerly laid aside have been worked in and a mass of new material has been studied. 1 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. 1have constantly combed the engineering periodicals and the newest books in both languages. My field is still engineering. Frequent referentes 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 qeeded 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. To 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. To bring al1 branches of civil engineering up to date. Special attention has been given to photogrammetry, soil mechanics, and airport construction. 3. To include the important terms peculiar to mining, shipbuilding, logging, sugar millirig, and oil-field operations.

A new feature is the notation of gender with al1 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 offici:il glossaries of the engineering societies. Many 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 thrend, but they cannot be combined into an equivalent for buttress thread. Most 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
