Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'суть' in all contexts; for the concrete 'lump' sense, use 'шишка', 'бугорок'.
- Do not confuse with 'nubby' (textured), which has no direct Russian equivalent.
Common Mistakes
- Using 'nub' as a verb (incorrect: 'He nubbed the issue'; correct: 'He got to the nub of the issue').
- Confusing 'nub' with 'hub' (a central point of activity vs. the central point of an idea).
