Where did hummock come from?

Having trouble telling a hummock from a hammock from a hillock? Not to worry: all three words refer to a small hill or earthen mound. Hummock, in fact, is an alteration of hammock; this 16th century pair share an ancestor with the Middle Low German words hummel (“small height”) and hump (“bump”), the latter of which is also a distant relative of our English word hump. As for the 14th-century vintage hillock, a version of the suffix -ock has been attached to nouns to designate a small one of whatever since the days of Old English. Note that the hilly hammock mentioned here is not related to the hammock offering a swaying repose between supports. That hammock comes from the Spanish hamaca, and ultimately from Taino, a language spoken by the original inhabitants of the Greater Antilles and the Bahamas.
