Thomas is a masculine given name. It is based on the Biblical Greek Θωμᾶς, which is itself a transcription of the Aramaic te'oma תאומא "twin", the Hebrew cognate being tə'ōm תאום.
"Tom" or "Thom" are abbreviations of Thomas, and "Tommy" is a common variant; "Tam" is a common abbreviation used in Scotland. Abbreviated written forms are "Thos" and "Th".
Feminine versions of this name are Thomasina, Tamsyn, Tamsin, Tasmina, Tasmino, Thomaida/Thomais, or Tammy.
Like Petros (Cephas) "the rock", Didymos or Thomas "the twin" is not in origin a given name but an epithet of a New Testament figure. The given name of Thomas the Apostle was Yehuda (Jude, Judas).
In the New Testament the designation was applied to Judas Thomas, the second Judas of the Apostles (hence his appellation "twin").
Use as a given name originates in the Early Middle Ages. Early known bearers of this name are Thomas the Presbyter (7th century) and Thomas the Slav (8th century).
The name becomes more common during the High Middle Ages, with notable bearers including Thomas of Bayeux (d. 1100), Thomas Becket (1118?−1170), Thomas of Britain (12th century), Thomas the Archdeacon (1200–1268), and Thomas Aquinas (1225–1270).
The Biblical Θωμᾶς has given rise to a large variety of spellings and forms in numerous languages.
