trick: [15] Trick comes from Old French trique, a variant of triche, which was derived from the verb trichier ‘cheat’ (source of English treachery). And this in turn probably came from Latin trīcarī ‘make difficulties, play tricks’ (source also of English extricate [17] and intricate [15]), a derivative of trīcae ‘difficulties, tricks’, whose origins are unknown. Tricky dates from the 18th century, its use for ‘difficult’ from the end of the 19th century.
