Where did hummock come from?

Hummock first appeared in English in the mid-1500s as an alteration of "hammock," another word which can be used for a small hill. This "hammock" is not related to the "hammock" we use to refer to a swinging bed made of netting or canvas. 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. The origins of the other "hammock" and the related "hummock" are still obscure, though they are related to Middle Low German hummel ("small height") and "hump" ("bump"). English also borrowed "hump," another word which can refer to a small hill or hummock.
