lum
/lʌm
/noun Scottish & Northern English
A chimney.With my eye to the lens, I had the city in my lap and could hoard to myself an unfair share of steeples and spires and cupolas; crow-stepped gables, garrets and all the Old Town's lums came rushing toward me....
- But when Christmas Eve came round the village lums were cold and black among the snowclouds and only the wheelhouse throbbed with life, a rosy glow on the foreshore.
Origin
Early 16th century: perhaps from Old French lum 'light', from Latin lumen.
