effect

effect: [14] Etymologically, an effect is that which is ‘accomplished’ or ‘done’. The word comes (probably via Old French effect) from effectus, the past participle of Latin efficere ‘perform, accomplish, complete’, or literally ‘work out’. This was a compound verb formed from the prefix ex- ‘out’ and facēre ‘make, do’ (source of English fact, factory, etc).

The English verbal use, ‘bring about’, is a 16th-century development based on the noun. (The similar affect also comes ultimately from Latin facēre, but with the prefix ad- ‘to’ rather than ex-.) Latin efficere is also the source of English efficacious [16] and efficient [14]. The feck- of feckless is an abbreviated version of effect.
=> efficacious, efficient, fact, factory, fashion, feckless
