- one-eyed person, someone blind in one eye
- tort, injury, offense
- someone who is thought to bring bad luck to a person they see
In Spanish, if someone experiences bad luck, it can be said that a "tuerto" (one-eyed person) has seen them. So common expressions such as "te ha mirado un tuerto" or "me miró un tuerto" meaning literally "a one-eyed person has seen you" or "a one-eyed person saw me" could be translated as "what rotten luck" or "I/He/She was jinxed".
