The name has been used by numerous kings, emperors, and popes, as well as notable figures like Alexander Hamilton and Alexander Graham Bell.In Serbian and Macedonian, the diminutive Aca is a familiar, affectionate form of Aleksandar, similar to other diminutives like Aco (Macedonian), Aleksa (Serbian), and Saša (Serbian). These forms are commonly used in everyday speech and informal contexts, reflecting the cultural tendency to shorten and personalize names. The name Aca is predominantly masculine and is found primarily in Serbia and North Macedonia.While the Wiktionary entry for Aca mentions an Etruscan romanization, that is unrelated to the Slavic name.
