Often used as a modifier in compounds (aspen grove, aspen leaf, aspen bark) rather than after a determiner alone. Plural 'aspens' refers to multiple individual trees; the bare noun 'aspen' is also used uncountably for the wood.

Common Mistakes

I planted an aspen tree leaves yesterday.
I planted an aspen tree yesterday.
say either 'an aspen' or 'an aspen tree', not both noun heads stacked.
The aspen is shaking by the wind.
The aspen is shaking in the wind.
use 'in the wind', not 'by the wind', for natural movement.

Synonym discussion

Sense: noun/1

All three are slender, fast-growing trees often seen in cool northern landscapes, but they are not interchangeable. 'Poplar' is the umbrella term for the whole genus Populus, which includes aspens, cottonwoods, and several other species; calling a tree a 'poplar' is correct but vague. 'Aspen' picks out the species whose leaves hang on flat stalks and tremble in even the lightest breeze — that visible shaking is the giveaway. 'Birch' belongs to a different family entirely (Betula); it is famous for its papery, peeling white bark, while aspen bark is smoother and chalkier. So you might say, 'The hillside was covered in poplars — mostly aspens, with a few white birches mixed in.'

Etymology

Proto-GermanicOld EnglishMiddle EnglishEnglish

The modern noun comes from Old English 'æspe', the name for the same tree. It originally appeared as an adjective form 'aspen' meaning 'made of or related to the æspe tree', and over time the adjective replaced the older noun. Related forms exist across the Germanic languages, such as German 'Espe' and Dutch 'esp', all pointing back to a shared Proto-Germanic root for this trembling-leafed tree.
