We’ve learned that the root “man” means hand.  For example, a manicure is a treatment for the hands.

During homeroom word study, we explored the prefixes re- and
un-.  Re means “again;”  for example, if you redo something, you do it again.  Un means “not.”  Something that is undone is not done.  We also learned that "super" means "above," while "sub" means "below."
