Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation like 'under clothes' as a phrase. It's a fixed lexical item.
- Do not use 'underwear' for sleepwear (пижама) – that's 'pyjamas'/'pajamas'.
- Remember it's uncountable; do not say 'an underwear' or 'underwears'.
Common Mistakes
- *I bought three underwears. (Correct: I bought three pairs of underwear/three items of underwear.)
- Confusing 'underwear' with 'lingerie' (which often implies fancy, women's underwear).
- Using in overly formal contexts where a specific term (e.g., 'briefs', 'vest') is better.
