The grammatical phenomenon of anacolutha; the practice or occurrence of sentences that shift their grammatical structure partway through.
From anacoluthon (not following) plus the suffix -ia forming an abstract noun. This describes the general phenomenon rather than individual instances.
Anacoluthia is so common in real conversations that linguists studying actual speech patterns find way more of it than in written formal English—our brains don't always plan complete sentences before we speak!
