Morphology

mountain + alder

This is a straightforward noun–noun compound where 'mountain' modifies 'alder', so a learner who knows both words will understand it denotes a type of alder associated with mountainous areas (i.e., a shrubby tree). Specific botanical details like exact size or leaf color are extra encyclopedic information, but the core meaning is compositionally transparent.

Etymology

Mountain alder may come from the simple picture of an alder tree growing by a mountain stream or on a wet slope, with the words mountain and alder naming the place and the tree. So, it means an 'alder' that lives on mountain banks and moist hills.
