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.
A third type of non-semantic grouping of written words is based on their length, i.e. the number of letters they contain. This type, worked out with some additional details, may prove useful for communication engineering, for automatic reading of messages and correction of mistakes. It may prove useful for linguistic theory as well, although chiefly in its modified form, with length measured not in the number of letters but in the number of syllables. Important statistical correlations have been found to exist between the number of syllables, the frequency, the number of meanings and the stylistic characteristics a word possesses. The shorter words occur more frequently and accumulate a greater number of meanings.
Finally, a very important type of non-semantic grouping for isolated lexical units is based on a statistical analysis of their frequency. Frequency counts carried out for practical purposes of lexicography, language teaching and shorthand enable the lexicographer to attach to each word a number showing its importance and range of occurrence. Large figures are, of course, needed to bring out any inherent regularities, and these regularities are, naturally, statistical, not rigid. But even with these limitations the figures are fairly reliable and show important correlations between quantitative and qualitative characteristics of lexical units, the most frequent words being polysemantic and stylistically neutral.
