Etymology tree Proto-Indo-European *-id- Proto-Indo-European *-yéti Proto-Indo-European *-idyéti Proto-Hellenic *-íd͏̌d͏̌ō Ancient Greek -ῐ́ζω (-ĭ́zō) Proto-Indo-European *-mos Proto-Indo-European *-mós Ancient Greek -μός (-mós) Ancient Greek -ισμός (-ismós)der. English -ism Ultimately from Ancient Greek -ισμός (-ismós), a suffix that forms abstract nouns of action, state, condition, doctrine, from the stem of verbs in -ίζειν (-ízein) (whence English -ize). Doublet of -ismus. Many English nouns in -ism are loans of Greek nouns in -ισμός (-ismós), often via Latin and French, such as Judaism, a learned English formation from Latin attested from c. 1500 and ultimately from Ancient Greek Ἰουδαϊσμός (Ioudaïsmós). In Late Latin, the -ismus suffix became the ordinary ending for names of religions and ecclesiastical or philosophical systems or schools of thought, thus chrīstiānismus (whence 16th c. Christianism) in Tertullian, a trend continued in Medieval Latin, with e.g. pāgānismus attested by the 8th century. From the 16th century, such formations became very common in English, until the early 18th century mostly restricted to either root words of Greek or Latin origin (heroism, patriotism) or proper names (Calvinism, Lutheranism). Productivity from root words with evidently non-Latin and non-Greek origin dates to the late 18th century (e.g. blackguardism). Reflecting this productivity, use of ism as a standalone noun is attested in Edward Pettit (1680) and becomes common from the mid-18th century. The narrowed sense of forming terms for ideologies based on the belief of superiority is based on coinages such as racism (1932) or sexism (1936) and productive since the 1970s.

Where this record stops

This page does not supply an independently verified sound-change sequence, first-use manuscript or complete family tree unless a cited analysis explicitly establishes one. Missing detail here is a limit of this record—not a claim that humanity knows nothing more.

An older meaning does not determine what a word must mean today. Follow the sources, preserve disagreements, and keep ancestry separate from interpretation.
