ap‧po‧si‧tion /ˌæpəˈzɪʃən/ noun [uncountable] technical
in grammar, an occasion when a simple sentence contains two or more noun phrases that describe the same thing or person, appearing one after the other without a word such as ‘and’ or ‘or’ between them. For example, in the sentence ‘The defendant, a woman of thirty, denies kicking the policeman’ the two phrases ‘the defendant’ and ‘a woman of thirty’ are in apposition.
