Answer:
My first half means container. Not a lot of people understand my language.
My rings are not worth much, but they do tell my age. What am I?
I am the kind of nut that is empty at the center and has no shell.
I come without being fetched at night hides away as soon as daylight strikes. Although I may look small I am much mightier than what you can imagine.
I am like thunder in your cranium
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
