"Blether" captures the Scottish ambivalence toward excessive talk — at once affectionate and mildly reproving. Used as both verb and noun, it describes idle gossip, rambling speech, or the person who produces it. In poetry it adds comic texture and social observation, gently mocking pretension or foolishness. Its sound — soft yet percussive — mirrors the quality it describes. Burns and later makars use it to deflate pomposity with characteristic Scots wit.

Blether is both verb and noun, and its range makes it enormously useful in characterisation. A "blether" as a person is someone who talks endlessly and emptily — a social type recognised across centuries of Scottish life. To "blether" is to engage in that talk oneself. The word has a slightly affectionate quality despite its critical meaning; calling someone a blether is not quite the same as calling them a liar. In poetry it often serves comic purposes, deflating pretension or capturing the rhythms of community conversation. Related terms include "clishmaclaver" (idle gossip) and "gaberlunzie" (wandering beggar/chatterer). Students should note how Burns uses speech and talk as poetic subjects in their own right.
