Origin & History of “stem”
The stem (OE) of a tree is etymologically the upright part, the part that ‘stands’ up. The word comes from prehistoric Germanic *stamniz, a derivative of the base *sta- ‘stand’ (which also produced English stand). The application to the ‘front of a vessel’ (as in from stem to stern) comes from the notion of an ‘upright beam’ at the prow (and originally the stern also) of a boat, which dates back to the Anglo-Saxon period. Stem ‘stop’ (13th c.) was borrowed from Old Norse stemma, a descendant of prehistoric Germanic *stamjan. this was formed from the base *stam- ‘stop, check’, which also produced English stammer and stumble.
