Etymology of ALPHANUMERIC CHARACTERS
The word "alphanumeric" is a combination of two separate words: "alpha" and "numeric".
1. "Alpha" comes from the first letter of the Greek alphabet, which is "alpha" (Α). It has its roots in the Proto-Semitic word "aleph" or "alef", meaning "ox". The symbol for "alpha" α represents the sound /a/ in the Greek language.
2. "Numeric" is derived from the Latin term "numerus", meaning "number". It refers to anything related to numbers or numerical systems.
When combined, "alphanumeric" refers to a character set that combines both alphabetical letters (alphas) and numeric digits (numerals).
