Evert means to turn inside out or outward, from Latin evertere, to overturn, on record since 1533. Some sea stars evert their stomachs through their mouths and digest prey outside their bodies — A.Word.A.Day’s gloss: they take dining out literally. Its lookalike avert shares the root vertere and differs only in prefix, out versus away: if the wind everts your umbrella, averting your eyes won’t help. David Foster Wallace used it for a Wimbledon gale that “everted umbrellas all morning.”
