Ideographic dictionaries are designed for writers, orators, translators who seek to express their ideas adequately.

A Reverse dictionary contains a list of words in which the entry words are arranged in alphabetical order starting with their final letters. The original aim of such dictionaries as to indicate words which contain rhymes. Now it is necessary for those, who study the frequency and productivity of word-forming elements.

CONTEXTUAL ANALYSIS. COMPONENTUAL ANALYSIS

The contextual method of linguistic research holds its own alongside statistical, structural and other developments. Like structural methods and procedures, it is based on the assumption that difference in meaning of linguistic units is always indicated by a difference in environment. Unlike structural distributional procedures (see §5.2, 5.3) it is not formalised. In some respects, nevertheless, it is more rigorous than the structural procedures, because it strictly limits its observations and conclusions to an impressive corpus of actually recorded material.

COMPONENTIAL ANALYSIS

A good deal of work being published by linguists at present and dealing with semantics has to do with componential analysis.1 To illustrate what is meant by this we have taken a simple example (see p. 41) used for this purpose by many linguists. Consider the following set of words: man, woman, boy, girl, bull, cow. We can arrange them as correlations of binary oppositions man : : woman = boy : : girl = bull : : cow. The meanings of words man, boy, bull on the one hand, and woman, girl and cow, on the other, have something in common.

This distinctive feature we call a semantic component or seme. In this case the semantic distinctive feature is that of sex — male or female. Another possible correlation is man : : boy = woman : : girl. The distinctive feature is that of age — adult or non-adult. If we compare this with a third correlation man : : bull = woman : : cow, we obtain a third distinctive feature contrasting human and animal beings. In addition to the notation given on p. 41, the componential formula may be also shown by brackets. The meaning of man can be described as (male (adult (human being))), woman as (female (adult (human being))), girl as (female (non-adult (human being))), etc.

Componential analysis is thus an attempt to describe the meaning of words in terms of a universal inventory of semantic components and their possible combinations.1

Componential approach to meaning has a long history in linguistics.2 L. Hjelmslev’s commutation test deals with similar relationships and may be illustrated by proportions from which the distinctive features d1, d2, d3 are obtained by means of the following procedure:

Morphological structure of english words. Morphemes . Free and bound forms

If we describe a wоrd as an autonomous unit of language in which a particular meaning is associated with a particular sound complex and which is capable of a particular grammatical employment and able to form a sentence by itself (see p. 9), we have the possibility to distinguish it from the other fundamental language unit, namely, the morpheme.

A morpheme is also an association of a given meaning with a given sound pattern. But unlike a word it is not autonomous. Morphemes occur in speech only as constituent parts of words, not independently, although a word may consist of a single morpheme. Nor are they divisible into smaller meaningful units. That is why the morpheme may be defined as the minimum meaningful language unit.

The term morpheme is derived from Gr morphe ‘form’ + -eme. The Greek suffix -erne has been adopted by linguists to denote the smallest significant or distinctive unit. (Cf. phoneme, sememe.) The morpheme is the smallest meaningful unit of form. A form in these cases is a recurring discrete unit of speech.

A form is said to be free if it may stand alone without changing its meaning; if not, it is a bound form, so called because it is always bound to something else. For example, if we compare the words sportive and elegant and their parts, we see that sport, sportive, elegant may occur alone as utterances, whereas eleg-, -ive, -ant are bound forms because they never occur alone. A word is, by L. Bloomfield’s definition, a minimum free form. A morpheme is said to be either bound or free. This statement should bе taken with caution. It means that some morphemes are capable of forming words without adding other morphemes: that is, they are homonymous to free forms.

According to the role they play in constructing words, morphemes are subdivided into roots and affixes. The latter are further subdivided, according to their position, into prefixes, suffixes and infixes, and according to their function and meaning, into derivational and functional .affixes, the latter also called endings or outer formatives.

When a derivational or functional affix is stripped from the word, what remains is a stem (or astern base). The stem expresses the lexical and the part of speech meaning. For the word hearty and for the paradigm heart (sing.) —hearts (pi.)1 the stem may be represented as heart-. This stem is a single morpheme, it contains nothing but the root, so it is a simple stem. It is also a free stem because it is homonymous to the word heart.
