The Collaborative International Dictionary of English v.0.48
Practise \Prac"tise\, v. t. & i.
See {Practice}.
[1913 Webster]
Note: The analogy of the English language requires that the
noun and verb which are pronounced alike should agree
in spelling. Thus we have notice (n. & v.), noticed,
noticing, noticer; poultice (n. & v.); apprentice (n. &
v.); office (n. & v.), officer (n.); lattice (n.),
latticed (a.); benefice (n.), beneficed (a.), etc. Cf.
sacrifice (?; n. & v.), surmise (?; n. & v.), promise
(?; n. & v.); compromise (?; n. & v.), etc. Contrast
advice (?; n.), and advise (?); device (?), and devise
(?), etc.
