To Quaff. v.a. [of this word the derivation is uncertain: Junius, with his usual idleness of conjecture, derives it from the Greek, κυαφίζειν in the Eolick dialect used for κυαθίζειν. Skinner from go off, as go off, guoff, quoff, quaff. It comes from coeffer, Fr. to be drunk.] To drink; to swallow in large draughts.
He calls for wine; a health, quoth he, as if
H'ad been abroad carousing to his mates
After a storm, quafft off the muscadel,
And threw the sops all in the sexton's face. Shakesp.
I found the prince,
With such a deep demeanour in great sorrow;
That tyranny, which never quafft but blood,
Would, by beholding him, hath wash'd his knife
With gentle eye drops. Shakesp. Henry IV. p. ii.
On flow'rs repos'd, and with rich flow'rets crown'd,
They eat, they drink, and in communion sweet
Quaff immortality and joy. Milton's Par. Lost, b. v.
