hummock

the word 'hummock' first appeared in english in the mid-16th century, referring to a hillock or a rounded knoll. its origins are obscure but it is likely an alteration of the middle english word 'hammock', which meant an area of fertile ground in a marsh, itself of uncertain origin. one plausible theory suggests it may be of algonquian origin, borrowed into english from early colonial encounters in the americas, where it was used to describe a small, wooded hill. over time, its meaning expanded beyond terrestrial geography to include specific features in icy landscapes, such as ridges on an ice field.

this word is considered a simplex form. it is a loanword of uncertain origin, likely from an obsolete english dialect term. its structure does not lend itself to segmentation into productive morphemes within modern english.
