Tatym is an uncommon but distinctive given name of Slavic origin, particularly from Ukrainian and Russian heritage. It is a diminutive form of the name Tetyana (Ukrainian) or Tatyana (Russian), which in turn are derived from Latin names like Tatiana, meaning "arrival" or "arriver." This suggests a familial association or perhaps a sense of welcome to the bearer's arrival into the world.
"Over the span of two decades (1998-2023), there's been a notable increase in babies named Tatym born annually, from an average of around 6 births per year between 1998 and 2003 to over 10 births per year thereafter. Interestingly, 2008 and 2009 both saw a peak with 21 births each."
