sharp-tongued

The compound 'sharp-tongued' is a metaphorical extension of much older concepts. The Old English root 'scearp' originally described a physical cutting edge, a meaning which broadened to describe keen senses and, by the 16th century, a harsh or severe manner of speech. 'Tongue', from Old English 'tunge', has been synonymous with speech and language since ancient times. The fusion of these two elements creates a vivid image where one's speech is likened to a sharp blade, capable of delivering cutting, critical, and hurtful remarks. This compound adjective, emerging in the late 16th century, perfectly encapsulates the idea of verbal acuity used for criticism rather than wit.

Structure: sharp (having a fine edge or point) + tongued (having a tongue of a specified kind) - sharp: From Old English 'scearp' (having a cutting edge, keen). In this compound, it functions as an adjective meaning severe or harsh. - tongued: From Old English 'tunge' (the bodily organ of speech). The suffix '-ed' forms an adjective meaning 'possessing or characterized by a (specified kind of) tongue'.
