Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'лёгковесный' for people; use 'незначительный человек', 'неавторитетный'. For objects, 'лёгкий' is correct.
- Do not confuse with 'легкомысленный' (frivolous) – 'lightweight' implies lack of power/substance, not necessarily silliness.
Common Mistakes
- Using 'light' instead of 'lightweight' for composite objects: 'a light jacket' (OK) vs. 'a lightweight jacket' (emphasises material property).
- Overusing the pejorative sense for objects where it's inappropriate: 'This philosophy book is lightweight.' (potentionally correct) vs. 'This aluminium frame is lightweight.' (literal, not pejorative).
