-an

a 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.

Compare -enne, -ean, -arian, -ician.
