Multiple Choice

The prefix BI- conveys which meaning?

The prefix BI- signals two. When you see BI- attached to a word, it shows there are two of something or a double occurrence. Think of bicycle (two wheels), bilingual (two languages), or bilateral (two sides). Because the meaning is two, this makes BI- the correct choice. The other numerical prefixes represent different counts: tri- for three, quad- or tetra- for four, hex- or sex- for six, and BI- doesn’t convey those numbers.
