Jairinho is in Origin.

Jairinho is the Portuguese affectionate diminutive of Jair (and sometimes Jairo), formed with -inho, denoting endearment or smallness. Jair traces back to the Hebrew Ya’ir (Yair), a name in the Hebrew Bible borne by a judge of Israel and other figures; it means “he will shine” or “he enlightens.” Thus Jairinho carries the sense of “little one who shines” or “dear bringer of light.”

The form is most prevalent in Brazil, where diminutives often function as everyday names and, since the late 20th century, occasionally as official given names. Usage skews informal - family, friends, sports and music circles - but it appears on birth records as well. Related variants include Jair, Jairo (Spanish/Portuguese), Yair/Yaïr (Hebrew, French), and Yahir (Spanish variant), with parallel diminutives such as Jairzinho in Portuguese. Rare feminine counterparts include Yaira and the Portuguese Jairinha.
