Archaic word used in Rooster Cogburn
I need some help here. I just saw Rooster Cogburn again (for who knows how many times before.) There is a scene where Rooster is telling Eula how long he has been on the scout and he says "five ..." And uses a word starting with an L - lanstrum, lunstrum, something like that. Eula doesn't know the word, so Rooster explains it is "five decades."
Anybody know the word and it's origin?
