Practice. [
1913 Webster]
" 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."
