all the words (the lexicon) of a language, including neologisms, dialect and slang words, and terminology. A vocabulary’s scope and composition depend on the nature and level of the speaker’s economic, social, and cultural life. A vocabulary is an organized system in which words are united or contrasted through various relationships of content, as exemplified by synonyms, homonyms, antonyms, and semantic fields.

Words in frequent and wide use constitute the active vocabulary, and specialized or rarely used words (archaisms, neologisms, and terminology) constitute the passive vocabulary. The boundaries between the active and passive vocabulary are not fixed, and over a language’s course of development words shift from one group to the other. Examples are Russian proshenie (“petition”), prisluga (“maidservant”), guverner (“tutor”), and gorodovoi (“policeman”), which have passed from the active to the passive vocabulary.

Certain words are actively used by all speakers of a language over a lengthy period of history, for example, names of parts of the body or natural phenomena, terms related to kinship, and words designating basic activities, traits, and qualities. Such words are termed the basic vocabulary and are subject to the fewest changes. Frequency dictionaries indicate the relationship between the active and passive vocabulary at a given stage of development, generally within the limits of certain styles, genres, or types of speech.

As society develops, vocabularies continually expand owing to the formation of words through derivation and the assimilation of borrowings. During various epochs words from Scandinavian, Finnish, Turkic, Church Slavonic, Greek, and later from Latin and the Romance and Germanic languages entered the Russian vocabulary, whose base consists of Common Slavic and native Russian words. The vocabulary of German has absorbed words from Latin, French, Italian, English, and several other languages. These layers of borrowed words within a language’s vocabulary reflect the cultural and historical ties between peoples and constitute a proof—sometimes the only proof—of contacts among ancient peoples. Vocabularies are recorded, although not completely, in dictionaries.
