A选项与语法意义的定义不符。Grammatical meaning refers to that part of the meaning of the word which indicates grammatical concept or relationships such as part of speech of words （nouns, verbs, adjectives, adverbs）, singular and plural meaning of nouns, tense meaning of verbs and their inflectional forms. Associative meaning is open-ended and indeterminate.故B选项正确; Affective meaning的定义是Affective meaning indicates the speaker’s attitude towards the person or thing in question. C选项错误。D选项“搭配是可以影响词的意义的”。E.g. pretty women 与handsome women.表达的是两种不同气质的女人。故D选项错误。选B
