Pain

After a longer-than-usual break for vacation, we resume with one of my all-time favorites:
la douleur = pain. E.g.
j'ai des douleurs dans le dos = to have a backache
avoir les premières douleurs = to go into labor
tu vas comprendre ta douleur! = you'll understand the meaning of suffering!
douloureux / douloureuse = painful
la douloureuse (literally "the painful one") = the bill
