coast is clear meaning
âThe coast is clearâ was such a vivid turn of phrase that it almost immediately came into use in contexts far from any water to mean simply âthe danger is overâ or âthere is no riskâ (âWith their supervisor gone for the afternoon, the coast was clear for the wastebasket basketball championshipsâ).
The phrase used in Spanish to mean âthe coast is clearâ is âno hay Moros en la costaâ. This means âthere are no Moors on the coastâ. Looking back to the time when the Moors took control of Spain, this clearly refers to the nautical meaning of coast.
