      African, Yoruban

  20. Gru

    • Description:

      Gru is an unusual masculine name that gained recognition primarily through the main character in the animated film series 'Despicable Me.' Before this cultural reference, the name had very limited usage globally. It may have origins as a shortened form of Eastern European surnames or as a nickname in several cultures. The name is extremely rare as a given name but has seen occasional use since the film's popularity beginning in 2010. Gru has a distinctive brevity that makes it memorable, with just one syllable and three letters. While some parents might choose it for its association with the reformed villain character known for his intelligence and eventual kindness, its rarity suggests most families still consider it too closely tied to the fictional character for mainstream use.
