empirical: [16] Despite their formal resemblance, empirical and empire are completely unrelated. Empirical comes ultimately from the Greek adjective émpeiros ‘skilled or experienced in’, a compound formed from the prefix en- ‘in’ and peira ‘attempt, trial’ (a relative of English expert, peril, pirate, and repertory). From this were derived successively the noun empeiría ‘experience’ and empeirikós, which English acquired via Latin empiricus.
