Thaj is an uncommon name of unknown origin and meaning. It consists of four letters: T, h, a, and j. The letter 'j' is often pronounced as a soft 'g', similar to the French 'j'. Therefore, Thaj may be phonetically closer to 'Tah-g'. As for its rarity, it is not listed among the top 1000 names in any country's records, making it quite unusual.
"Thai was quite popular as a baby girl's name in 1999, with five newborns given this unique moniker."
