- Forms adjectives, usually from proper nouns.
- Almost all English words ending in "ean" are originally from Latin (Caesarean) or Greek (Euclidean). A few were later formed by adding -an to a stem or word ending in -ea (Korean), -es (Andean), or a silent -e (Boolean).
- used to indicate origin or place of birth (such as from a certain city or region), or occasionally nationality (e.g. Ardeal (“Transylvania”) + -ean → ardelean (“Transylvanian”), București (“Bucharest”) + -ean → bucureștean (“Bucharestian”)
