Dialectal Variation
British vs American Usage
Differences
Spelling variation: 'by-product' is overwhelmingly preferred in both varieties. 'Coproduct' is a rare, hyper-technical variant in specialised fields like pure mathematics.
Connotations
In everyday use, 'coproduct' is essentially non-existent. 'By-product' is the standard term with neutral-to-slightly-negative connotations (e.g., waste). In mathematics, 'coproduct' is a precise, neutral technical term.
Frequency
'Coproduct' is exceptionally rare in general English. Its use outside of advanced mathematics or highly specialised technical reports would be marked and potentially confusing.
