(Greek: a meadow; a pasture; an abode; a place for eating; by extension, "distribution of an acute, necrotizing ulcerative process involving mucous membranes of the mouth or genitalia")
Don’t confuse this element with the Greek nomo- which means "law" or another Latin nom- meaning "name".
This element is closely related to nomad- which means “wander, moving around for pasture or grazing for herds or flocks”.
