Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation. Russian 'хештег' is a direct loanword and is correct. Do not use 'решетка' (the physical grate/symbol) to mean the social media concept.
Common Mistakes
- Writing 'hash tag' as two words (standard spelling is one word: hashtag).
- Including spaces or punctuation within the hashtag phrase itself (e.g., #my day is wrong; #myday is correct).
