Etymology: From Middle English -ishen, -ischen, -issen, from Old French -iss-, -is- (a termination of the stem of some forms [present participle, etc.] of certain verbs), from Latin -ēscere, -īscere (an inchoative suffix), the formative -esc-, -isc- (-sc-, Greek -σκ- (-sk-)) being ultimately cognate with English -ish (Etymology 1). See -esce, -escent, etc.
- An ending found on some verbs; see usage notes.
