Linguistics
Semantic Notes

Dialectal Variation
British vs American Usage
Differences
While known in the UK as a North American tree species, the term is far more common in North America, especially in forestry, lumber, and historical woodworking contexts.

Frequency
Much more frequent in North American English, particularly in regions where the tree is or was native (e.g., Midwestern USA, Ontario).

- Misspelling as 'rockelm' (should be two words or hyphenated: rock-elm).

No, 'rock elm' functions only as a compound noun (for the tree or its wood) or as a noun used attributively (e.g., 'rock elm timber').
They are different species. Rock elm (Ulmus thomasii) has harder, heavier wood, often grows on drier sites, and has distinctive corky ridges on younger branches, unlike the American elm (Ulmus americana).
