Root Explanation

Alphanumerical is formed from "alpha" (from Greek "ἄλφα", meaning the first letter of the Greek alphabet) and "numerical" (from Latin "numeralis", meaning relating to numbers). The term combines these elements to refer to a system that includes both letters and numbers.

Memory Tip

Think of 'alpha' as the first letter and 'numerical' relating to numbers — together, they describe a system that includes both letters and numbers.
