"Smoor" describes a slow, suffocating suppression — fire smothered by ash, passion dampened by circumstance, life constrained by oppressive conditions. In Scots poetry it appears in contexts of weather, emotion, and social critique, evoking the heavy, pressing quality of forces that extinguish rather than strike. The word has a slightly sinister softness — that initial "sm" and the long vowel — that suits its meaning of slow, silent obliteration. Burns and later poets use it to describe both natural and social oppression with equal force.

Smoor has a particular intensity, suggesting not the clean extinction of a blown-out candle but the slow, oppressive suffocation of something covered and deprived of air. A fire is "smoored" rather than extinguished when peat is heaped over it to keep it alive overnight — an ancient domestic practice that gives the word a secondary meaning of preservation through suppression. In verse, the "smooring" of a fire at night is a ritual laden with domestic symbolism, and the old Gaelic smooring prayers are among the most beautiful survivals of folk religious practice. Students should note this paradox: to "smoor" can mean to destroy but also to preserve. This ambivalence gives it unusual range as a metaphorical verb.
