partisanship

Etymology

It is formed from English partisan + -ship.^[2][3] Partisan, a zealous supporter of a party or cause, recorded from 1555, is from Middle French partisan, from Italian partigiano (“member of a faction, partner”), in northern dialects also partesano and partisano,^[2][3][4] from parte (“part, party”),^[2][3] from Latin pars (“a part, share; a party or faction”).^[3][5] Etymonline traces the Latin noun to Proto-Indo-European *pere- (“to grant, allot”).^[3]

Earliest recorded meaning

Earnest or passionate adherence to a party or faction: 1831, according to Etymonline and the 1989 edition of the OED.^[3][6] The revised OED (2005) gives its first quotation from Thomas Carlyle's Sartor Resartus (1834).^[2]

Semantic evolution

The word was formed after the noun partisan had long meant a devoted supporter of a party, cause or person (from 1555), and after the adjective had taken on the sense "one-sided, prejudiced" (from 1805 in the OED, while Etymonline dates the political adjective to 1842).^[2][3] From the start, partisanship covered both loyal support and its failing, a lack of impartiality.^[2][6] The Historical Thesaurus files it with the words for factionalism among the terms for parties and factions.^[7] Merriam-Webster Unabridged distinguishes simple adherence to a cause, group or political party from a blind and unreasoning adherence that amounts to bias.^[5]
