Omologare

Recently this space explained that the term GTO—as in Pontiac GTO—was an Italian acronym for the phrase "Gran Turismo Omologato." Even more fascinating, Wordsmith points out that omologato comes from the verb homologate. Etymologically, it's from Latin homologare (to agree); from Greek homologein (to agree or allow). The verb—omologare in Italian—means: "to register a specific model of a motor vehicle to make it eligible to take part in a racing competition."
