the.com/sure thing

The verbal handshake that commits you to nothing while sounding like everything.

means An affirmative reply meaning 'yes, definitely' — or, in practice, 'yes, probably, ask me later.'

from A straightforward American colloquialism from the 1800s, pairing 'sure' (certain) with 'thing' to mean a certainty — first used literally for guaranteed bets or outcomes, then drifted into casual speech as a breezy way of saying 'yes.' No hidden trick in its roots — the gap between its confident sound and its noncommittal use is purely a modern social habit, not an etymological one.
