hair-splitter
Over-precise arguer
A hair-splitter is someone who makes unnecessarily fine distinctions, insisting on trivial differences that don't matter in practice.
The term is almost always critical, suggesting pedantry or evasiveness: Don't be such a hair-splitter—you know what I meant.
Related forms include hair-splitting (noun and adjective) and the verb split hairs.
