Root Explanation

Alphanumeric → It is formed from "alphanumerical" (a combination of "alpha" from Greek "alpha" (the first letter of the Greek alphabet, representing letters) and "numeric" from Latin "numericus" (meaning relating to numbers)). The word "alphanumeric" refers to a character set that includes both letters and numbers.

Memory Tip

Think of 'alpha' representing letters and 'numeric' relating to numbers — together, they form a system that includes both letters and numbers.
