I don't mean to make it grammatically correct I mean does English need them?
I can't seem to find a use case other than it's "legacy" in English, but that is never a reason to keep something around.
For example, would there ever be a confusion of "hell" and "he'll"? What about "theyll" or "they'll" or "he's" and "hes".
A friend brought up this use case:
Tim: "How do I get up there?"
Rodney: { "Well think." | "We'll think." }
Except that is even flawed because technically "well" in the first example needs a comma after like:
Rodney: { "Well, think." | "We'll think." }
This would clear this confusion up.
I saw killtheapostrophe.com years ago and it got me thinking and so I brought it up with my grandmother, who has a Ph. D. in linguistics, and she agrees with him, however it got brought up again on Twitter and I was curious what others who love linguistics think about it.
