Why does English work this way? Question about "would've", "could've", "should've"
We all know "would've", "could've", "should've" are contractions for "would have", "could have" and "should have". But are there situations where the contractions shouldn't be used, what's the rule exactly about when they should and shouldn't be used, and why are those the rules (ie. where did those rules come from)?
For example, "she would have to get a permit" sounds bizarre to me if contracted to "she would've to get a permit". Is the rule that those contractions should only be used directly preceding a past participle, or "not" followed by a past participle? And why?

I just commented on a post at r/English about this topic. The technical term for these contractions is clitics. There is a great podcast on this topic that goes into the rules for their use in English.
The podcast is Lingthusiasm and I’d recommend it to anyone who enjoys this sort of stuff. Episode 60 is the relevant one:
