Final answer:
The statement that a lexical set is a group of words with the same topic, function, or form is true. Lexical sets focus on semantics and are useful for language learning, grouping similar thematic vocabulary for easier recall. They are distinct from linguistic discussions of the form and function of words within grammar.
Step-by-step explanation:
A lexical set is indeed a group of words, but it is specifically related to vocabulary within the same category. This means that the statement 'A lexical set is a group of words with the same topic, function or form' is True. Lexical sets are often used for the efficient learning and teaching of a language, grouping words by topics such as 'furniture', 'weather', or 'emotions', rather than their grammatical form or the function they serve in a sentence. This approach helps language learners to expand their vocabulary in a topical, themed manner, making it easier to recall and utilize words in relevant contexts.
The concept of form versus function in linguistics distinguishes how a word is categorized in terms of parts of speech (its form), from how it behaves in a sentence (its function). While form is static, function may change depending on the context of the sentence. For example, a verb in its base form can function as a noun, such as in the sentence 'Swimming is fun.'
Understanding both form and function is crucial for mastering a language's grammar, which is the set of rules used to convey meaning through the use of a lexicon. Grammar encompasses syntax, the arrangement of words to create sentences, and semantics, the meaning derived from words. Lexical sets focus on semantics by grouping words based on meaning rather than syntax.
