Latin word of the week!

Well seeing as school starts again on Monday I thought it was time to start my homework, one of my homeworks being latin vocab learning. So I've decided to start a latin word of the week post where every week i will post a completely random and useless latin word from my vocab list for as long as I can be bothered.
So the first ever latin word of the week is.........................dum dum DUM..............' rudis = a stick or rod'
