A Teachta Dála (IPA: [ˈtʲaxtə ˈdɑːlə]) is a member of Dáil Éireann, the lower chamber of the Oireachtas (Parliament) of the Republic of Ireland. The official translation of Teachta Dála is Deputy to the Dáil,[1] a more literal translation is Assembly Delegate. In English the abbreviation TD is normally used, with TDs as the plural (Irish: Teachtaí Dála).
The initials "TD" are placed after the surname of the elected TD. For example, the current Taoiseach (head of government) is "Brian Cowen, TD". The style used to refer to individual TDs during debates in Dáil Éireann is the member's name preceded by Deputy (Irish: an Teachta): for example, "Deputy Kenny", "an Teachta Ó Cionnaith".
