a grammatical construction where two nouns or noun phrases are placed together, are not joined by a conjunction such as "or" or "and," and where each noun has the same syntactical relationship to the rest of the sentence
Apposition is the placement of two or more semantically equal elements (i.e. nouns or noun phrases) next to each other that share the same syntactic function or place. Example:â€œThe Lord God, the God of Abraham, is the one true God.â€ (The noun phrases, â€œ Lord Godâ€ and â€œGod of Abraham,â€ both hold the same syntactic position of subject)
Apposition is a grammatical construction in which two elements, normally noun phrases, are placed side by side, with the second element serving to define or modify the first. When this device is used, the two elements are said to be in apposition. For example in the phrase "my friend Alice" the name "Alice" is in apposition with the word friend.
