- look around suspiciously
- look at the time a lot/or phone
- disappear into a corner/something
- look suspicious
- walk around glaring
those are some ideas, i hope they help :)
A root word is a portion of a base that do not stand alone and have no meaning for themselves.... but,a base word is a word that does not have any other words added either at the beginning or its ending....
