The linguistic performance of a person is unique because their linguistic competence is matchless. Phonological and orthographical feature constitute only superficial aspect. There are morphological, syntactic, semantic, and pragmatic features that make one's linguistic code distinct from that anybody else. This is why every person has their own idiolect which, like a fingerprint, has no replica.
