- Do not use Cyrillic transcription (эм-эс дос) in formal English writing; use 'MS-DOS'.
- Be aware that 'DOS' alone can refer to other disk operating systems (e.g., DR-DOS), not just Microsoft's.
Common Mistakes
- Writing as 'msdos', 'MSdos', or 'Ms-Dos' (standard is MS-DOS).
- Using it as a verb (e.g., 'I will MS-DOS the computer').
- Pronouncing it as a word /'mzdɒs/ instead of sounding out each letter for 'MS'.
