I find this word and its derivations somewhat interesting, and kinda amusing, as with many clumsily borrowed loanwords from English.
First off, there is the word «секси». From what I gather, this is an indeclinable adjective... is this correct? Are there any other indeclinable adjectives in Russian? I've never come across any others.
Then we have the word «сексапильный», which I find generally hilarious (it's like saying "sex appeal-ish" in English). Is this a synonym for «секси»? Are there any other words using this root? «сексапильность», perhaps? :lol:
Finally, are there any Russian words for sex that are more native than this? Surely you Russians had some words for sex before you stole them from english... :p
