Definiteness and Specificity FAQ

What is definiteness?

The property by which a noun phrase presents its referent as identifiable or uniquely recoverable in context.

What is specificity?

No. An indefinite noun phrase can be specific, and English does not mark specificity with one dedicated article.

How do corpora help?

They reveal article choices across recurring noun phrases, genres and reference contexts.
