Final answer:
The 'lexicon' of a language refers to its complete dictionary, encompassing all words for names, ideas, and events. Lexicon is part of the larger linguistic structure that includes grammar, consisting of syntax and semantics, which governs how words are used.
Step-by-step explanation:
The term for all the words for names, ideas, and events that make up a language's dictionary is lexicon. A lexicon encompasses the entire vocabulary of a language, including all terms used to express objects, actions, and abstract concepts. It's distinguished from grammar, which is the set of rules that dictates how these words are used to convey meaning, including syntax and semantics.
Languages evolve over time, with new words being added and others falling out of use. The English dictionary, for instance, now contains over 600,000 recognized words. Words in a language can be borrowed from other languages, particularly names for family members and pronouns. These words and their organization into sentences allow for the communication of concrete as well as abstract ideas and feelings.
