The phrase いってらっしゃい is derived from the verb 行く (いく), which means "to go," and the auxiliary verb ～てくる, which indicates an action that is done and then comes back. The full form is 行って来なさい, which is a command meaning something like "Go and come back." Over time, it has evolved into a polite and friendly parting phrase. The final "い" is dropped and the "なさい" becomes "らっしゃい" as a polite form. いってらっしゃい is a contraction of the more formal and older form.
