Origin and meaning

'AJ' is an initialism derived from American English naming conventions (often representing initials like A.J. or Junior) that gained popularity in the late 20th and early 21st century. In the Philippines, it is frequently registered directly onto birth certificates as a standalone legal first name rather than just an informal nickname.

Originates as an English initialism (commonly short for names like 'Andrew John', 'Anthony Jr.', etc.) that has become widely used directly as an official registered given name in the Philippines.
