Gilbert

You might remember this name growing up from the cat in the animated children’s show Caillou with the blue spot over his eye. Originating from German, the boy’s name Gilbert means “bright pledge.” This name receives its significance from Gil deriving from gīsil, meaning “pledge,” and bert from behrt, meaning “bright.” Like the name of the character from the crime show CSI: Vegas, Gil is a short form of Gilbert, and it makes for a lively little nickname.
