It goes without saying that Jair Bolsonaro has ruined this name. I can't hear this name without thinking of him or his deluded, violent supporters. I think he's the worst president we've ever had.
/ʒaˈiʁ/ is the Brazilian Portuguese pronunciation of the name as this Wikipedia article is referring to a Brazilian politician. Replying to Jenkowelten's comment on Jul/21/2021https://en.wikipedia.org/wiki/Jair_Bolsonaro
We named our son Jair Ziggy in 1996. Ziggy after his maternal uncle (Sigmar) not Bob Marley's son nor Ziggy Stardust, I assure you. First heard the name in my early 20's from a (Dutch) work colleague and fell in love with it, not knowing the meaning at that stage. As Jair is now nearly 24 this year I am yet to see him live up to the name meaning "he will lead or shine etc" still, he's a good son.
