As per my reading I do not find any occurance of the word "Tarawih" in hadith literature , was such a word known at the time of Prophet pbuh or is it that Taraweeh is just a special name given to the Tahajjud Prayer in Ramdan.

Tarwiha, the singular of Tarawih, refers to the period of rest between every four rakat of the prayer. Salat at-Tarawih was so-named because of these rests, which differentiated it from the normal Salat at-Tahajjud.
As far as I know, Salat at-Tarawih is the same as Salat at-Tahajjud, only performed earlier and with frequent rests to make it easier on the people during Ramadan.
