Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- The word is a compound, not 'верхний регистр' translated word-for-word. In English, it's a single lexeme: 'uppercase', not 'upper case'.
- As a verb, it's directly 'to uppercase' (e.g., uppercase the first letter), which might feel unnatural.
Common Mistakes
- Writing it as two words: 'upper case'. While sometimes seen, the single-word form is standard for the adjective and verb.
- Using it as a countable noun incorrectly: *'an uppercase' (correct: 'an uppercase letter' or 'uppercase').
