Be bound to do sth

[mrwroc]

Is "be bound to do sth" in meaning "certain" old fashioned or not? For example:
You're bound to feel nervous before your exam.

I found "I'll be bound" is Old fashioned. Does it mean each Sentence with "bound" in meaning "certain" like the Sentence above is Old fashioned too?

Is "be bound to do [STRIKE]sth[/STRIKE] something" [STRIKE]in meaning[/STRIKE] when "bound" means "certain" old-fashioned or not? For example:
You're bound to feel nervous before your exam.

I [STRIKE]found[/STRIKE] read/heard/discovered that "I'll be bound" is old-fashioned. Does it mean each sentence with "bound" [STRIKE]in[/STRIKE] meaning "certain", like the sentence above, is old-fashioned too?

Note my corrections above. I have no idea why you capitalised "sentence" or "old" each time. Remember to reserve capital letters for the first letter of every sentence, the word "I", the first letter of proper nouns, and (where relevant) acronyms.
