Ok.Just last clarification
So will it be "My Sister's husband-to-be is coming home"
Also suppose if I am referring to him as a brother -in-law so can I say
" Hey My intended Brother -in-law is coming" or It shoud be" My Sister's intended is coming'."Which sounds better
My sister's intended is coming home = correct.
My sister's intended is coming = correct.
My intended brother-in-law is coming = incorrect. Messy though it seems, this can be said as "My brother-in-law-to-be is coming"!
"Intended" only works when you are referring to the person in relation to the person they are actually going to marry. "Intended" basically means "intended spouse" so you can't say "My intended spouse brother-in-law..."
Please also note, as I have stated in
both my previous responses - you do not put a capital S on sister or sister-in-law or, as you have now done, a capital B on brother-in-law!!!!
