Meaning and history
Tad is an English masculine diminutive of Thaddeus and is also occasionally used for Thomas. Thaddeus is the traditional English form of an Aramaic name borne by one of Jesus’s apostles, but its original meaning is uncertain; proposed connections with words for “heart” or “breast” are debated. As a nickname for Thomas, it instead belongs to a name meaning “twin” in Aramaic. Notable bearers include American politician Tad Cochran and American film director and animator Tad Stones.
Tad moved from #923 to #983 for boys between 1988 and 1989. Its highest annual birth count came in 1966, with 265 births.
