What is a Grammatical Construct?

[DChristyParker]

Can you please define the term Grammatical Construct? I also would like a few examples...

Thanks

Welcome.

Definition: A group of words that form a constituent of a sentence and are considered as a single unit.

Example: Apposition. Two typically adjacent nouns referring to the same person or thing stand in the same syntactical relation to the rest of a sentence. For example, in "the rally of the opposition Labor Party", "Labor Party" is in apposition with "opposition".

Example: Adjunct. A clause or phrase added to a sentence that, while not essential to the sentence's structure, amplifies its meaning. For example, in We waited for several hours.

All the best.
