Riot, What is dat Yasuo Shout

English is not good, but I want to ask because I thought the question.

What Was Yasuo trying to say when upon using skill? Refer to the English Wiki, for Example...

Upon using Steel Tempest, "飛ん(Fly)!" "風(Wind)!"

For translation of Wind,　only describes a noun in Japanese. Fly is not possible as the word anymore.

As Japanese translation, Fly should translate as "飛べ" or "飛び上がれ". Translation of Wind is believed that "風よ" is the best.

Or maybe, the first place it is only reference to the Japanese, It's referred to as Japanese, Is it a mistake from the outset?
