Questions & Answers about У меня есть вопрос насчёт фрилансера.
Why is the word фрилансера in the Genitive case here?
It is required by the preposition насчёт (meaning "regarding" or "concerning"). This preposition always takes the Genitive case, so the masculine noun фрилансер gets the standard animate Genitive ending -а.
Could I just use о (about) instead of насчёт in this sentence?
Yes, saying У меня есть вопрос о фрилансере (using the Prepositional case) is grammatically perfectly fine. However, насчёт is frequently used in conversational Russian to mean "on the subject of" or "regarding," often implying there is a specific issue, task, or detail you need to sort out.
I sometimes see на счёт written as two words. Is that a mistake here?
In this context, it would be a mistake. As a preposition meaning "regarding," насчёт is always written as one word. If you write на счёт as two words, it is a preposition plus a noun literally meaning "onto the account" (for example, transferring money на счёт фрилансера — to the freelancer's bank account).
фрилансер is obviously a loanword. Do all imported English words decline like normal Russian words?
Most of them do! If a borrowed word ends in a consonant (like фрилансер, менеджер, or ноутбук), Russian naturally treats it as a standard masculine noun and applies all the regular case endings. Usually, only loanwords with non-standard endings for Russian nouns (like такси or меню) remain undeclined.
