Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "скользить" (to slide/glide), which implies continuous contact. "Skim" implies intermittent or minimal contact. "Просматривать" is a good equivalent for reading, but lacks the physical motion sense. "Снимать пенку/сливки" is the equivalent for the 'remove from surface' meaning.
Common Mistakes
- Using 'skim' to mean 'study quickly but thoroughly' (it implies missing details).
- Confusing 'skimmed milk' (processed) with 'semi-skimmed milk'.
- Incorrect preposition: 'skim on the surface' (use *over* or *across*).
