What does suki mean in Russian?

"Suki" is not a word in the Russian language. It's likely you're thinking of a word from a different language, possibly Japanese.

In Japanese, "suki" (好き) means "like" or "love."

If you're looking for a Russian word for "like," you'd use "нравится" (nravitsya), which is a verb meaning "to like" or "to be pleasing to."

For "love," you would use "любить" (lyubit').
