-an
-ana suffix occurring originally in adjectives borrowed from Latin, formed from nouns denoting places (Roman; urban ) or persons (Augustan ), and now productively forming English adjectives by extension of the Latin pattern. Attached to geographic names, it denotes provenance or membership (American; Chicagoan; Tibetan ), the latter sense now extended to membership in social classes, religious denominations, etc., in adjectives formed from various kinds of noun bases (Episcopalian; pedestrian; Puritan; Republican ) and membership in zoological taxa (acanthocephalan; crustacean ). Attached to personal names, it has the additional senses “contemporary with” (Elizabethan; Jacobean ) or “proponent of ” (Hegelian; Freudian ) the person specified by the noun base. The suffix -an, and its variant -ian also occurs in a set of personal nouns, mainly loanwords from French, denoting one who engages in, practices, or works with the referent of the base noun (comedian; grammarian; historian; theologian ); this usage is especially productive with nouns ending in -ic (electrician; logician; technician ). See -ian for relative distribution with that suffix.
