Lexicology (from Gr lexis ‘word’ and logos ‘learning’) is the part of linguistics dealing with the vocabulary of the language and the properties of words as the main units of language.
The term vocabulary is used to denote the system formed by the sum total of all the words and word equivalents that the language possesses.
The term word denotes the basic unit of a given language resulting from the association of a particular meaning with a particular group of sounds capable of a particular grammatical employment. A word therefore is simultaneously a semantic, grammatical and phonological unit.
As to the information afforded by learner’s dictionaries lexicographers and methodologists seem to have agreed that there should be a whole series of them. There must be a group of dictionaries presenting different aspects of the vocabulary: showing mainly the semantic structure of words (explanatory), presenting the syntagmatic relations between words (dictionaries of collocations), providing information: about the word’s structure (derivational), supplying synonymous and antonymous words, etc.
Another grouping of dictionaries reflects the practice of teaching different aspects of speech. The word-books having as their goal the ability to read scientific and technical literature in a foreign language will need a vast word-list ensuring adequate comprehension of written speech. Teaching oral speech habits requires a dictionary that contains a selected list of active words explained from the point of view of their use.
Since learners of different linguistic background will have different pitfalls in mastering the same language, will need different directions for use, different restrictive remarks, each pair of languages requires its own dictionaries, dictionaries based on a contrastive study of the learner’s native tongue and the language to be learned.1
In this connection it must be said that Hornby’s dictionary, with all its merits and advantages, has an essential demerit — it does not take into account the user’s linguistic background, so it cannot foresee and prevent the possible language problems of this or that national group of English learners.
Not long ago Soviet lexicographers came to the opinion that separate reference books are called for teachers and learners. As far as dictionaries of English go, perhaps the first attempts at producing dictionaries for teachers are the reference books Adjectival Collocations and Verbal Collocations.
Those are the main types of dictionaries considered necessary to ensure the process of foreign language teaching. As to the present state of learner’s lexicography, it may be characterised as just coming into being, as the already existing dictionaries are few in number and they do not make a system, rather some separate links of a system.
As to the information they provide they may be divided into two groups: those giving equal attention to the word’s semantic characteristics and the way it is used in speech (these may be called learner’s dictionaries proper) and those concentrating on detailed treatment of the word’s lexical and grammatical valency (dictionaries of collocations).
To learner’s dictionaries proper issued in English-speaking countries we may refer, for example, The Progressive English Dictionary and An English Reader’s Dictionary by A. S. Hornby and E. С Parnwell designed for beginners, as well as Oxford Advanced Learner’s Dictionary of Current English by A. S. Hornby and The New Horizon Ladder Dictionary of the English Language by J. R. Shaw with J. Shaw for more advanced students.
Oxford Advanced Learner’s Dictionary of Current English by A. Hornby has achieved international recognition as a most valuable practical reference book to English as a foreign language. It contains 50,000 units and is compiled on the basis of COD to meet the needs of advanced foreign learners of English and language teachers. It aims among other things at giving detailed information about the grammatical and partly lexical valency of words.
The New Horizon Ladder Dictionary includes 5000 of the most frequently used words in written English. It is called Ladder Dictionary because the words are divided in it into five levels or ladder rungs of approximately 1000 each, according to the frequency of their use (a figure in brackets attached to each word shows to which thousand the word belongs).
Compiled in our country is the English-Russian Dictionary of Most Commonly Used Words prepared by V. D. Arakin, H. M. Weiser and S. K. Folomkina under Prof. I. V. Rakhmanov’s direction. This is a vocabulary minimum of 3250 words, typical word-groups and phraseological units selected for active mastery in Soviet secondary school.
The Learner’s English-Russian Dictionary by S. Folomkina and H. Weiser does not, strictly speaking, belong to the group of dictionaries under consideration, as it is designed for use by English-speaking students of the Russian language, but is helpful as well when learning English. It contains about 3500 words.
The word-books given above differ in many respects: they are either monolingual or polylingual, they provide different information, they differ in the kind of the intended user (learners of the English language who have reached different stages in the course of their studies, adults or children of different linguistic background — English-speaking learners of Russian) and in aim (an aid to oral speech — the development of reading and writing skills) and in other features. However these dictionaries have some traits in common that distinguish them from the word-books considered in the preceding sections. They all aim at teaching how to speak, write, etc., while the tendency in modern English lexicography is not to prescribe as to usage, but to record what is actually used by speakers.
Dictionaries of collocation contain words which freely combine with the given head-word. The few reference books of this kind known to us belong to the pen of foreign compilers. For example, A. Reum’s Dictionary of English Style is designed for the Germans, Kenkyusha’s New Dictionary of English Collocations is intended for the Japanese, Adjectival Collocations in Modern English by T. S. Gorelik and Verbal Collocations in Modern English by R. Ginzburg, S. Khidekel, E. Mednikova and A. Sankin are designed for Russian school teachers and students of English.
Each of the two dictionaries of collocations prepared by Soviet linguists presents the collocability of 375 words that are used in Soviet school text-books. The presentation of the word’s grammatical and lexical valency is based on identical principles.
Compilers of learner’s dictionaries have to tackle the same cardinal problems as those of ordinary explanatory and translation dictionaries, but they often solve them in their own way, besides they have some specific policies to settle on to meet the needs of language learners to whom the book will be addressed.
The common purpose of learner’s dictionaries is to give information on what is currently accepted usage, besides most compilers seek to choose the lexical units that foreign learners of English are likely to need. Therefore not only are obsolete, archaic and dialectal words excluded, but” also technical and scientific terms, substandard words and phrases, etc. Colloquial and slang words as well as foreign words of common occurrence in English are included only if they are of the sort likely to be met by students either in reading or in conversation. Moreover some of the common words may be omitted if they are not often encountered in books, newspapers, etc. or heard over the radio and in conversation.
Space is further saved by omitting certain derivatives and compounds the meaning of which can be easily inferred.
Alternative spellings and pronunciations are avoided, only the more accepted forms are listed.
Various criteria have been employed in choosing words for learner’s dictionaries. In the first place the selection of words is based on the frequency principle.
Frequency value, an important characteristic of lexical units, is closely connected with their other properties. That is why the word-counts enable the compiler to choose the most important, the most frequently used words.
However many methodologists and compilers of learner’s dictionaries have a tendency to exaggerate the significance of the frequency criterion. The research done in different countries (in our country and in France, for example) has shown that the frequency tables, helpful ‘as they are in the compilation of a vocabulary minimum, do not in themselves present the vocabulary minimum. While it is indisputable that every high-frequency word is useful, it is not every useful word that is frequent (e.g. carrots, fork, stamp, etc.). Consequently frequency cannot be the only point to be considered in selecting items for learner’s dictionaries as well as for other teaching materials. It must be complemented by some other principles, such as the words’ collocability, stylistic reference, derivational ability, semantic structure, etc.1
The order of arrangement of meanings followed in learner’s dictionaries is usually empiric, that is beginning with the main meaning to minor ones. Besides the following principles of arrangement are considered proper for language learners: literal uses before figurative, general uses before special, common uses before rare and easily understandable uses before difficult. Each of these principles is subject to the limitation “other things being equal” and all are subject to the principle that that arrangement is best for any word which helps the learners most.
E.g. in Hornby’s entry for commit the first meaning is ‘perform’ (a crime, foolish act, etc.) and its primary meaning ‘entrust’ is given as its second meaning.
But this is not always the case. For instance, the first meaning of the word revolution given by Hornby is ‘act of revolving or journeying round’ and not ‘complete change, great reversal of conditions, esp. in methods of government’, which is more common nowadays. Thus the compilers preserve the historical order of meanings in this case.
In monolingual learner’s dictionaries the same types of definitions are used, as in ordinary monolingual explanatory word-books, but their proportion is different. Encyclopaedic definitions are usually used more rarely, the role of descriptive definitions is much greater.
Compare, for instance, the definition for coal taken from the Ladder Dictionary with that from COD given above.1
coal n. a black, hard substance that burns and gives off heat.
It would be wrong to think however that the definitions in learner’s dictionaries are always less complete than in the dictionaries designed for native users. More often than not these definitions are not so condensed in form and they are more complete in content, because the compilers have to make up for the user’s possible inadequacy in command of the language and lack of knowledge of some realia.
In learner’s dictionaries cross-references are for the most part reduced to a minimum.
Compilers of learner’s dictionaries attach great importance to the language in which the definition is couched, the goal being to word them in the simplest terms that are consistent with accuracy. Some compilers see to it that the definitions are couched in language which is commoner and more familiar to the language learner than the words defined.
Some lexicographers select a special defining vocabulary held to be the commonest words in English or those first learnt by foreigners. For example, in the International Reader’s Dictionary the word-list of 24,000 items is defined within a vocabulary of 1490 words selected by M. West.
In some learner’s dictionaries pictorial material is widely used as a means of semantisation of the words listed. Pictures cannot only define the meanings of such nouns as dike, portico, domes, columns, brushes, etc., but sometimes also of adjectives, verbs and adverbs.
E.g. in Hornby’s dictionary, the definitions of the adjective concentrated, the verb clasp and the adverb abreast are illustrated with the pictures of concentrated circles, clasped hands, and boys walking three abreast.
1. The numerous linguistic dictionaries of the English language may be grouped by the following criteria: 1) the nature of their word-list, 2) the information they contain, 3) the language of the explanations, 4) the intended user.
