- hush (v.)
- 1540s (trans.), 1560s (intrans.), variant of Middle English huisht (late 14c.), probably of imitative origin, with terminal -t lost probably by being mistaken for a past tense suffix. The sounds chosen presumably for "being sibilations requiring the least muscular effort and admitting of the faintest utterance" [Century Dictionary]. Related: Hushed; hushing.

Hush up "suppress talk for secrecy's sake" is from 1630s. Hush-money "bribe paid to ensure silence" is attested from 1709.
