noun / verb

alibi

AL-uh-bye/ˈæləbaɪ/

An explanation intended to establish freedom from blame.

The café's timestamped security image supports the suspect's alibi.

An investigator compares two security-camera stills with identical timestamps: one shows a masked burglar breaking into a jewelry shop, while the other clearly shows the seated suspect elsewhere, paying at a café counter.
Etymology

Latin alibi means “elsewhere.” Its legal use turns that location into a defense: evidence that people were elsewhere when the crime occurred supports their innocence.
