-an

Etymology

It is inherited from Middle English -an, regularly earlier -ain, -ein and -en,^[1][2] borrowed from Old French -ain and -ien,^[1][3][4] and directly borrowed from Latin -ānus,^[5][6][3][7] feminine -āna, neuter -ānum, an adjective suffix meaning of or belonging to,^[3][5][8] as in silvānus, urbānus and Rōmānus.^[3][5] Etymonline and Wiktionary trace it to Proto-Indo-European *-nós.^[6][1]

Semantic evolution

The French form was at first kept in some borrowings and later gave way to -an.^[3][8] A few pairs keep both with a difference in meaning, such as human and humane, urban and urbane, and german and germane;^[3][2] arcane and mundane have -ane with no such contrast.^[2] The suffix became productive, especially on names of places, and adjectives so formed are often used as nouns.^[8][5] Merriam-Webster records a use for geological periods, epochs and series, as in Cambrian.^[9] The longer forms -ian and -ean are variants.^[9][10] The form -ean comes from words such as Mediterranean and European.^[9][10]

Usage notes

In chemistry the suffix also occurs in the names of compounds, an unrelated use: Merriam-Webster takes it from an alteration of -ene, -ine and -one,^[9] and the OED records an arbitrary ending proposed by Davy for chlorides, now obsolete.^[5] The OED also lists the Old English inflectional ending -an, used in the weak noun declension (later the -en of oxen) and in the infinitive of verbs, both unconnected with this suffix.^[5]
