Etymology

From Middle English mote, from Old French mote (“mound, embankment”); compared also to Old French motte (“hillock, lump, clod, turf”), from Medieval Latin mota (“a mound, hill”), of Germanic origin, perhaps via Frankish *mot, *motta (“mud, peat, bog, turf”), from Proto-Germanic *mutô, *mudraz, *muþraz (“dirt, filth, mud, swamp”), from Proto-Indo-European *(s)mut- (“dark, dirty”). Cognate with Alemannic German Mott, Mutte (“peat, turf”), Bavarian Mott (“peat, turf”), dialectal Dutch mot (“dust, fine sand”), Saterland Frisian mut (“grit, litter, humus”), Swedish muta (“to drizzle”), Old English mot (“speck, particle”). More at mote, mud, smut. As term for a business strategy, popularized by American investor Warren Buffett.

Example Sentences

• "Moreover, where older firms might have to stave off competitors and engage in practices like predatory pricing to keep the competition at bay, platform monopolies have a built-in moat.
