Word Origin and History for callow

Old English calu "bare, bald," probably from West Germanic *kalwaz (cf. Middle Dutch calu, Dutch kaal, Old High German kalo, German Kahl), perhaps from Latin or Celtic. From young birds with no feathers, meaning extended to any young inexperienced thing or creature (1570s). Apparently not from Latin calvus "bald."
