FLING/ˈflɪŋ/n.
Forensic Linguistics
The language is the evidence.

FLING does not name the author. It examines the writing — the letters, the ciphers, and the habits of language that run through them — and records what each method of examination can and cannot show. Claims are attributed, methods are named, and disputes are preserved.
