An Irishman, about equal to Pat or Paddy. Sometimes we find the word Teague-lander. Teague is an Irish servant in Farquhars Twin Rivals; in act iii. 2 we find the phrase a downright Teague, meaning a regular Irish character blundering, witty, fond of whisky, and lazy. The name is also introduced in Shadwells play, The Lancashire Witches, and Teague ODivelly, the Irish Priest (1688).
