Ritira (re-TEE-ra): (verb) Dismiss, return (something), retire, retreat, chase away, withdraw.
Note: Some also say litira. Also, I've never heard ritira used for "chase away," it's in the Topping dictionary, but I don't know how to use it that way, and I'd be confused to hear it used that way. If you've heard it like that, I'd appreciate a couple examples.
"Ki ora maritira hao gi che'cho'?" = "What time do you get off work?"
"Ma ritira yo' gi che'cho'-hu." = "They dismissed me from work."
"Ritira gi sagå-mu." = "Return to your place."
