Norwegian lesson:
tømmermenn, n. literally ‘timber men’, i.e. lumberjacks, though it’s been a while since anyone actually thought of axes, saws and timber when they heard the word, I suspect. Nowadays, you have tømmermenn, and it basically means you have a hangover.
Considering the price of alchohol in Norway, it’s rather surprising quite how often this word comes into use…
