Tammi is a girl’s name of multiple origins. It may be a shortened form of Tamara, which derives from the Hebrew name Tamar, meaning “date palm tree.” It may also be a diminutive of Tamsin or Thomasina, both feminine forms of Thomas, which derives from the Aramaic name Te’oma, meaning “twin.” Also spelled Tammie and Tammy, this upbeat name was most popular in the 1960s, giving it a charming retro feel. A famous bearer was Motown singer Tammi Terrell.
