Here is a worksheet on the Latin word root inter. It means between and among. As you have no doubt already recognized, this is an extremely productive root in English, growing such high-frequency words as interfere, intercept, and interim (all present in this document), among many others. Inter should not be confused with intra and intro, which mean within, inward, inside, and into (a worksheet on which is forthcoming).
