meu

From Latin mēum (“umbelliferous plant, Meum athamanticum”), from Ancient Greek μῆον (mêon), probably from μεῖον (meîon, “lesser”) for its small size. The English form came perhaps via Middle French meu, a word with a single isolated attestation from the 14th century which only began to appear consistently from 1568, by which time the word was established in English.
