tendentious (English)

Where does "tendentious" come from?

The English adjective 'tendentious' was formed from 'tendency' combined with the suffix '-ious', modeled after the German word 'tendenziös'[1]. The German term itself derives from 'Tendenz'[3], which was relatinized from the French 'tendance'[4]. These European terms ultimately trace back to the Latin participle 'tendens' and verb 'tendō', meaning to stretch out or to be inclined to, rooted in the Proto-Indo-European root meaning to stretch or draw[2][5][11].

Open questions

• The ultimate derivation of the Latin adjective tener is disputed between a Proto-Indo-European root meaning to stretch and a separate root meaning soft or tender. [8]
