'sharp-billed' originates from English, specifically the words 'sharp' and 'bill', where 'sharp' comes from Old English 'scearp' meaning 'cutting, keen' and 'bill' comes from Old English 'bile' meaning 'beak' or 'projecting piece'.

'sharp' developed from Old English 'scearp' and 'bill' from Old English 'bile'; the compound adjective 'sharp-billed' is a modern English formation created by combining the adjective 'sharp' with the noun 'bill' to describe birds and similar animals.

Initially, the elements meant 'keen/cutting' (sharp) and 'beak/projection' (bill); combined, the meaning has remained descriptive and now specifically denotes 'having a sharp or pointed beak'.
