According to the Armenian-Turkish language researcher Sevan Nişanyan[1], it is of Persian origin, with a likely link to the Old Turkish "Tez", which means escaping. Going very off-topic here but it's interesting if you like etymology: In modern Turkish "Tez" means "in a short time", but also "thesis", which we borrowed from French who took it (ultimately) from Old Greek "títhēmi" which is evolved from the root "*dhē-" (to put) in the Proto-Indo-European language.
