касательно vs насчёт

kasatelno vs naschyot — concerning (formal) vs about/regarding

What it really means

Касательно is a formal preposition meaning “concerning” and governs the genitive: касательно проекта. Насчёт means “about” or “regarding,” usually in practical conversation, and also governs the genitive. Насчёт is written as one word and has a different meaning from на счёт, “into the account.”

Examples in natural speech

Касательно договора направляем отдельное письмо.
Regarding the contract, we are sending a separate letter.
Касательно сроков решение примет комиссия.
As for the deadlines, the committee will decide.
Я хотел спросить насчёт билетов.

Common mistakes

Both prepositions take the genitive: насчёт поездки and касательно поездки. Keep насчёт “about” separate from на счёт “onto/into the account,” which has a noun and different stress and syntax.

Memory tip

Касательно belongs in a memo; насчёт belongs in a question to a friend.
