Translation Traps (for Russian speakers)
- Avoid using 'множество' (just 'many') for the negative connotation; use 'избыток', 'переизбыток'. The word 'плетора' is a direct borrowing but is rare and very formal/medical.
Common Mistakes
- Using it with uncountable nouns incorrectly: 'a plethora of water' (better: 'a plethora of water brands'). Treating it as plural: 'Plethora are...' (It's singular: 'Plethora is...').
