Etymology

Inherited from Middle English alder or aldre, from Old English alor, and ultimately from a Germanic tree name also reflected in Old High German elira. Alder by itself names both the Alnus tree or shrub and its wood, so alder tree is a transparent expanded form rather than a separate botanical lexeme.
