Dialectal Variation
British vs American Usage
Differences
The term is used identically in both varieties, but it refers to trees native to western North America and Asia. A British speaker might be less likely to encounter the tree naturally but would use the same term in botanical contexts.
Connotations
In both varieties, it carries connotations of traditional craftsmanship (tanning), forestry, and botany. No significant difference in connotation.
Frequency
Equally low frequency in both varieties. Slightly higher potential frequency in American English due to the tree's native range in California and Oregon.
