Dialectal Variation
British vs American Usage
Differences

Connotations
Identical connotations of strength, support, and central importance. The metaphorical sense ('moral backbone') is equally strong.
Frequency
Slightly more frequent in American English in technical contexts (e.g., 'internet backbone'), but the difference is marginal.

Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'backbone' as 'хребет' in all contexts. While correct for anatomy, for 'internet backbone' use 'магистральная сеть' or 'основная сеть'. For 'moral backbone', use 'сила воли', 'твёрдость характера'. 'Spine' and 'backbone' are often synonyms, but 'spine' is more common for the literal body part in everyday speech.
Common Mistakes
- Using it as a countable plural in metaphorical senses (e.g., 'the backbones of society' is acceptable, but 'he has backbones' is wrong). Confusing 'backbone' with 'backbone' as a single, central entity versus multiple supporting elements.
