originThe adjective is first attested in 1487, in Middle English, the verb in 1557; borrowed from Latin mātrīculātus, perfect passive participle of mātrīculō (“to register”) (see -ate (etymology 1, 2 and 3)), from mātrīcula (“public register”), a diminutive of Latin mātrīx (“list”). By surface analysis, matricul(a) + -ate.
