I am a real newbie in this forum (I registered here 2 minutes ago...). My question cannot or does not want to be answered by Google... 

My question is: do I need to put the word “future” before the word “wife-to-be”? Or is it already clear from the single “wife-to-be” that it refers to my prospective wife?

I only learned English at school as a teenager and unfortunately this rule wasn't explained at the time...

Therefore, I will be very grateful for any answers! (͡๏̯͡๏)(͡๏̯͡๏) 

Best regards
