Linguistics
Semantic Notes
Purists distinguish between 'acronyms' (pronounced as words, e.g., NATO) and 'initialisms' (pronounced as letters, e.g., FBI). In common usage, 'acronym' often covers both. The term is also used for pronounceable abbreviations from syllables, not just initials (e.g., radar).

Connotations

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'abbreviation' (сокращение) in general. 'Acronym' is a specific type. The Russian borrowing 'акроним' is directly equivalent.
- Avoid calquing 'to decipher an acronym' as 'расшифровать акроним'; use 'to spell out what the acronym stands for'.
Common Mistakes
- Using 'acronym' for any abbreviation (e.g., 'Dr.' is not an acronym).
- Pronouncing it /ˈæk.rə.naɪm/ (incorrect).
- Writing: 'The acronym, NATO, it means...' (redundant pronoun).
