Webster's Dictionary (GCIDE)

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. [1913 Webster]
