Terry m
English: in the Middle Ages this was a Germanic name (composed of elements meaning ‘tribe’ and ‘power’ see DIETRICH (SEE Dietrich)) introduced to England by the Normans in the form T(h)ierri. (A fuller form is represented by the name of the Emperor Theodoric, where the spelling has been influenced by association with THEODORE (SEE Theodore); See also DEREK (SEE Derek) and DERRICK (SEE Derrick).) In modern English use Terry seems at first to have been a transferred use of the surname, which is derived from the medieval given name, and later to have been taken as a pet form of TERENCE (SEE Terence).
