'sharp-peaked' originates from Modern English, specifically formed by combining the adjective 'sharp' and the adjective 'peaked'. 'sharp' originates from Old English 'scearp', where 'scearp' meant 'cutting' or 'keen', and 'peak' ultimately comes from Old English 'pīc' and Old Norse 'pikr', where 'pīc/pikr' meant 'point'.

'sharp' changed from Old English 'scearp' to Middle English 'sharp' and eventually to modern English 'sharp'. 'peak' entered Middle English in forms such as 'pike'/'peke' (influenced by Old Norse) and evolved into modern English 'peak'. The compound 'sharp-peaked' is a straightforward modern combination of the two elements.

Initially, 'sharp' meant 'cutting' or 'keen' and 'peak' meant 'point'; over time the combined form came to be used adjectivally to describe things that 'have a sharply pointed summit or tip', a meaning consistent with its parts.
