gully

The word 'gully' traces its lineage back to the Latin 'gula', meaning 'throat'. This term passed into Old French as 'goule' and its diminutive form 'goulet', which referred to a narrow passage or channel, much like a throat. In the 16th century, English adopted and adapted the term, initially as 'gullet' for the anatomical feature and later as 'gully' to describe a narrow, eroded channel in the earth, drawing a direct metaphorical link between the shape and function of a throat and a landscape feature carved by water. This evolution from a body part to a geographical feature exemplifies a common pattern of semantic extension based on shared characteristics of narrowness and passage.

The word 'gully' is a simplex form. It is derived from the Middle English 'gole' or 'gullet', meaning 'throat' or 'water channel', which itself came from the Old French 'goulet' (a diminutive of 'goule', meaning 'throat').
