Disease. The Saxon-English had about fifty pure Teutonic names of diseases, to the main of which we now give Latin names. They were ranked under some few head-words.
Cwealm (qualm) meant mostly a deadly or many-killing epidemic, as the plague or cholera, which they would call a mancwealm (manqualm). Of this word we have left only qualm with qualmish.
Adl (our addle) was another main word for disease, as an unsoundness. From this word we have addle-headed and an addled egg.
