Persistence mechanism: shared conventions of the medium (linguistic grammar, notational systems, artistic traditions), biological communication systems, and the normative practices of interpretation within a community.

A neologism is a specific kind of expression — namely, a newly coined or recently adopted word/expression. A competent speaker would say 'a neologism is an expression.' Pinned sense: linguistic expression (Law 11d: sense of 'expression' = words/phrases conveying meaning, per its accepted definition).
- cmrpiwhrh07aod1nl51zyps2i← INSTANCE_OF
A paraphrase is a specific kind of expression — restating something in different words. The competent-speaker test passes: 'a paraphrase IS an expression.' Nearest kind is expression.
