Etymology of nutgall
The term 'nutgall' dates back to the 14th century, derived from the Old English words 'nut' and 'gall', referring to the growths on oak trees. The Latin term 'galla' also refers to oak apples or nutgalls. The growths are caused by various species of gall wasps, which deposit their eggs into plant tissue, inducing the formation of these unique structures.
