Bloom and lahey"s 3 components of speech: form (structure, content (meaning, use (pragmatics) Mlu: # of morphemes/# of utterances (typically 100). Open class words/content words: lexical categories, carry the meaning. Closed class words/function words: functional categories, serve a grammatical function. Phrase: groups of words that are structurally related but do not make up a clause or sentence. Do not contain a subject and a predicate. Clause: a group of words that includes a subject and a predicate but is not necessarily grammatically complete. Sentence: a group of words that includes a subject and a predicate and is structurally complete. Determiner: articles, adjectives, and demonstrative pronouns (this, that, these, those) that modify the noun; can be called a modifier. Simple sentence: noun phrase + verb phrase. Complex sentence: main clause (independent) + subordinate clause (dependent). Ex) the flowers are growing in the garden. Ex) the boy will go to school because he is not sick.
