Origin: 1375–1425; late Middle English < Latin intrīcātus, past participle of intrīcāre to entangle, equivalent to in-in-2 + trīc(ae) perplexities + -ātus-ate1
c.1470, from L. intricatus "entangled," pp. of intricare "to entangle, perplex, embarrass," from in- "in" + tricæ (pl.) "perplexities, hindrances, toys, tricks," of uncertain origin (cf. extricate).
