Greetings
I was talking to someone, and I was asking how to say "How do you say (some english word) in russian?". He told me it would be "Как будет (word) на русском", but I thought it should be "Что будет (word) на русском"

Как будет (word) на русском litterly translates to "How will be word in russian?", which is why I'd think it would be "Что будет (word) на русском"

Any clarification on when to use что and как? Thanks
