Learning Prefixes and Suffixes
Knowing the Greek and Latin roots of several prefixes and suffixes (beginning and endings attached to words) can also help us determine the meaning of words. Ante, for instance, means before, and if we connect bellum with belligerant to figure out the connection with war, we'll know that antebellum refers to the period before war. (In the United States, the antebellum period is our historybefore the Civil War.) Prefixes showing quantity
