Certain of the stylistically marked vocabulary strata are, in a way, exclusive: professional terminology is used mostly by representatives of the professions; dialects are regional; slang is favoured mostly by the young and the uneducated. Not so basic vocabulary. These words are used every day, everywhere and by everybody, regardless of profession, occupation, educational level, age group or geographical location. These are words without which no human communication would be possible as they denote objects and phenomena of everyday importance (e. g. house, bread, summer, winter, child, mother, green, difficult, to go, to stand, etc.).
The basic vocabulary is the central group of the vocabulary, its historical foundation and living core. That is why words of this stratum show a considerably greater stability in comparison with words of the other strata, especially informal.
Basic vocabulary words can be recognised not only by their stylistic neutrality but, also, by entire lack of other connotations (i. e. attendant meanings). Their meanings are broad, general and directly convey the concept, without supplying any additional information.
For instance, the verb to walk means merely "to move from place to place on foot" whereas in the meanings of its synonyms to stride, to stroll, to trot, to stagger and others, some additional information is encoded as they each describe a different manner of walking, a different gait, tempo, purposefulness or lack of purpose and even length of paces (see Ch. 10). Thus, to walk, with its direct broad meaning, is a typical basic vocabulary word, and its synonyms, with their elaborate additional information encoded in their meanings, belong to the periphery of the vocabulary.
