PREFACIO

Cuando Ios originales del Engineers' Dictionay quedaron listos en 1943, lasegunda guerra mundial estaba en su apogeo y esto llev6 a la casa editora y a1autor a convenir de que el libro no debia exceder de unas cuatrocientas cincuentap&ginas. Algb material debib ser retirado y aunque el libro resultante tratabadetenidamente de ingenieria civil, no pudo contener muchos tbrminos usados enotras ramas de la ingenieria.

Poco tiempo despues de su publicacih yo me retire del trabajo activo deingenieria y desde entonces he tenido amplias oportunidades para dedicarme a lacompilacih de un diccionario m4s extenso. El material que debib ser retiradose ha agregado ahora y se ha estudiado una gran cantidad de material nuevo.He consultado con muchos amigos de la Ambrica Latina y en cada viaje he trafdoconmigo publicaciones t6cnicas de diversas clases como fuente de t6rminosespaiioles. Constantemente he escudrifiado las revistas de ingenieria y 10slibros nuevos publicados en ambos idiornas.

El campo de acci6n sigue siendo la ingenieria y las referencias frecuentes a laqufmica, la geologfa o la metalurgia no significan que estas materias esth total-mente abarcadas en este libro. Cada una de ellas necesitaria un volumen aparte.

Los tkrminos incluidos de estas u otras materias son aquellos regularmenterequeridos en un trabajo o estudio de ingenieria. Igual criterio se hha seguidoenla selecci6n de algunos pocos terminos de finanzas, seguros y transportes.

Al ampliar la obra mis principales propbsitos han sido 10ssiguientes:

Abarcar Ia ingenieria el6ctrica y rnechica en manera mucho m$s amplia.La radio que no se rnencion6 para nada en la primera edici6n ha recibido cuida-doso estudio. Sc han incluido t4rminos importantes de la televisibn.

Poner a1 dia todos 10s ramos de la ingenieria civil. Se ha dado especial atenci6n

a la mechnica de 10s suelos, a la fotograrnetrfa y a1 proyecto y construccidn deaeropuertos.

Incluir Ios t6rrninos mbs importantes correspondientes a minerfa, arquitecturanaval, explotaci6n forestal, industria azucarera y campos petroliferos.

Una nueva adici6n es la indicaci6n de ghero de 10s substantivos en espafiol.

El objeto de un diccionario thico es proporcionar inhrmaci6n que no seencuentra en otra partc. Se supone que el diccionario de Webster incluye todasy cada una de las palabras del idioma ingl&, alin las mbs tbcnieas, pero no abarca

Ias frases que figuran en glosarios oficinles de Ins sociedndes de ingenieria.Muchas de las palabras de esr;e libro se encuentran tambi6n en 10s mejoresdiccionarios generales inglk-espaiiol. Buttress se encuentra en cuulquiera deellos, igualmente que thread, pero no buttress thread. Aguja y tarnbih infernalse encuentran, pero no aguja injemal. La mayoria de mis esfuerzos se han

concentrado en el registro de significados o equivalentes de locuciones que nopueden expresarse con una sola palabra-

Lanomenclatura de piezas de maquinaria requiere un constante uso de buencriteria. Cada fabricante tiene su propia lista de piezas para cada maquinay algmas rnAquinas constan de tantas que llegan a1 millar. Las partes principalesde una msiquina deben enumerarse y con ellas, fuera de 10s tdrminos comocojinete, leva, tornillo, resorte, rodillo y vdlvula, deben identificarse con unnombre la gran mayoria de las piezas componentes.

A pemr de algunos consejos adversos recibidos, yo creo todavia que lasdefiniciones estkn fuera de lugsr en un diccionario tBcnico bilingiie. El interesadoque busca en un libro como Bste el tbrrnino slip-ring moior quiere encontrar elequivalente aceptado en espaiiol y no una descripci6n del motor. Las de-finiciones aumentarian mucho el volurnen del Iibro. La prhctica seguida hasido la de definir un thnino solamente a1 carecer de un equivalente satisfactorioy en algunos casos para evitar ambigiiedades.

Es obvio que existen en este libro rnuchas palabras, tanto en espafiol comoen ingks, que tienen otros significados ademtis de 10sanotados. Se han omitido10s significados no t6cnicos, asi como aquellos que pertenecen a la bothica,zoologia y otras ciencias de inter& muy relativo para el ingeniero.

Algunos de 10s thminos de la obra original han sido criticados IlamAndolos"ma1 espafiol". Un critic0 me ha dicho que la incorporaci6n de tales tbrminosa un diccionario tiende s perpetuarlos y a perjudicar el idioma. Mi punto devista es que la exactitud de 10s terrninos tecnicos en cualquier idioma es esta-blecida por 10s t6cnicos que 10s crean y 10s usan, y la tarea del cornpilador del

diccionario es la de registrar ssu uso. En esta obra se trata de dar n 10s t6cnicosde habla inglesa de la Ambrica del Norte la terminologia de ingenieria usada en10s palses de habla espafiola de Amhrica y viceversa. Terminos tornados depublicaciones oficiales, de especificaciones de ingenieros y de libros de textoseconsideran expresiones usadas y "aceptadas". Para muchos miles de thminosen ingl6s no hay equitralente en "buen espaiiol" si se sigue el criterio de la RealAcademia. Esta es la raz6n de la diferencia entre unos 125,000 t6rminos enel dccionario de la Academia y de unos 500,000 en el de Webster.

Los equivalentes en espafiol de marcas de fBbrica o de comercio en ingles

presentan un problema. La simple aseveraci6n de que estos nombres no puedentraducirse no soluciona el problema, porque muchas traducciones son de usocorriente en 10s paises de habfa espafiola. Muchos de estos tbrminos ya se hanincorporado a otros diccionarios en espafiol o en espaiiol-inglbs. Hay propietariosde marcas de fhbrica o comercio quienes han creado expresamente equivalentesen espaiiol para usarlos en su propaganda. Yo he seguido la practica de incluirtodo thrmino de esta clase que he encontrado en buen uso te'cnico. Debe notarseque muchos tkrminos en inglks de esta claw se han hecho tan conocidos que conla sanci6n de Webster regularrnente se escriben sin mayhcula. Para la mayorfa

PREFACE

Under the war conditions of 1943, when the original Engineers' Dictiomywas in preparation, publisher and author agreed that the book ought to be keptdown to about 450 pages. Some material had to be laid aside, and although theresulting book dealt thoroughly with civil engineering, it could not go very farwith 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

J

a mass of new material has been studied. I have consulted many friends inLatin America and from each trip have brought back technical publications ofmany kinds to be worked over for my Spanish terms. I have constantly combedthe engineering periodicals and the newest books in both languages.

My field is still engineering. Frequent references to chemistry, geology, ormetallurgy do not mean that these subjects are covered. Each of them wouldneed a volume of its own. Terms of these and other sciences here included arethose which are regularly needed in connection with engineering work. Thesame 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 all branches of civil engineering up to date. Special attentionhas been given to photogrammetry, soil mechanics, and airport construction.3. To include the important terma 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 foundelsewhere. Webster's is supposed to include every word in the English languageno matter how technical, but it does not cover the phrases that are listed inofficial glossaries of the engineering societies. Many of the words in this bookwill be found also in the best English-Spanish general dictionaries. Broad isfound 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 buttressthreud. Most of my effort has gone into pinning down the phrases.

The listing of machine parts calls for the constant use of judgment. Every

i. manufacturer has his own list of parts for each machine, and some machineshave parts running into the thousands. The principal members of a machine

xi '

PREFACE

must be listed, and with these, plus terms like bearing, cam, bolt, spring, roller,and valve, equivalents of the vast hajority of part names may be written easily.

In spite of some advice to the contrary I still believe that defiriitions are outof 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 thatterm and is not looking for a description of a slip-ring motor. Definitions ~vouldadd greatly to the book's bulk. My practice has been to define a tern1 only indefault of a satisfactory equivalent or occasionally to avoid ambiguity.

Obviously there are many words here, both Spanish and English, that havemeanings other than those given. Nontechnical meanings luve usually beenignored, as have those which belong to botany, zoology, or other sciences thatdo not concern the engineer.

Some of the terms in the original book have been criticized as "had Spanish."

One critic tells me that the listing of such terms in any dictionary tends toperpetuate them and does an injury to the language. My own view is thatthe 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 P;record this usage. This book aims to give the North American technical manthe accepted engineering terminology of Spanish America, and vice versa.Terms taken from official publications, from engineers' specifications, and fromtextbooks are "accepted" terms. For many tllousancIs of English technical

terms there are no ((good Spanish" equivalents, if the Royal Academy is to bethe criterion. This is the principal reason for the difference between some125,000 entries in the Academy dictionary and 5OO,OOO in Webster's.

Spanish equivalents of English trade names are a problem. The simplestatement that proprietary names cannot be translated does not cover the situa-tion because they are regularly being translated in Spanish-speaking countries.Many such terms have already appeared in other dictionaries, both straightSpanish and English-Spanish. There are owners of English trade names whohave deliberately created Spanish equivalents for use in their advertising.My rule has been to include every term of this kind that I have found in goodtechnical use. It is to be noted also that there are a great many trade nanles in

English that have become so well known that, with Webster's approval, theyare reguIarly written without the capital letter. For most of the terms in thisclass there are Spanish equivalents cqually well established.

Many friends who advised with me in the preparation of the original bookhave again been helpful. 1 am particularly grateful to Mr. George C. Bunkerwith whom I have spent many hours in Caracas. ~esides giving freely of hisown time he introduced mc to Venezuelan engineers from whom I obtainedmaterial of great value. For terms of sanitary engineering, both in English andin Spanish, I have to thank Mr. Edmund B, Besselievre of the Dorr Co. arid
