Of or pertaining to; an adjectival suffix appended to various words, often nouns, to make an adjective form. (Often added to words of Latin origin, but also used with words of other origins. When a word ends in a, -n is used instead.)
Appended to nouns to form an agent noun. (When males with a profession are distinguished from females, males are -an, females -(i)enne.)
Used to form a noun from an adjective; especially, to form the noun referring to the state, property, or quality of conforming to the adjective's description.
Used to form other nouns, especially abstract nouns.
