Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid using 'максимум' as an adverb in English (*'I'll be there maximum at five'). Use 'at the latest' or 'at most'.
- Do not confuse with 'максимальный', which is an adjective. In English, 'maximum' can be both noun and adjective.
Common Mistakes
- Using 'maximum' as an adverb (*'It costs maximum ten pounds').
- Using 'a maximum' without 'of' when followed by a number (*'a maximum 50 people'). Correct: 'a maximum of 50 people'.
- Incorrect plural: *'maximums' is rare; 'maxima' is the technical/scientific plural, but 'maximums' is increasingly accepted.
