Tarawih is a sunnah mu'akkadah - meaning a verified sunnah that the Prophet used to do consistently. He technically used to pray qiyaam al-layl (optional nightly prayers) year-round, out of devotion to Allah. It must be clarified that tarawih is essentially considered qiyam, but it was given the name tarawih - which literally means "to rest and relax" - in reference to how the sahabah (companions of the Prophet) and righteous used to literally rest every four raka'as because of how lengthy the prayer was.
