Regex to match words with hyphens and/or apostrophes

I was looking for a regex to match words with hyphens and/or apostrophes. So far, I have:

(w+([-'])(w+)?[']?(w+))

and that works most of the time, though if there's a apostrophe and then a hyphen, like qu'est-ce, it doesn't match. I could append more optionals, though perhaps there's another more efficient way?

Some examples of what I'm trying to match: Mary's, High-school, 'tis, Chambers', Qu'est-ce.

use this pattern

(?=S*['-])([a-zA-Z'-]+)

Demo

(?=                 # Look-Ahead

  S                # <not a whitespace character>

  *                 # (zero or more)(greedy)

  ['-]              # Character in ['-] Character Class

)                   # End of Look-Ahead

(                   # Capturing Group (1)

  [a-zA-Z'-]        # Character in [a-zA-Z'-] Character Class

  +                 # (one or more)(greedy)

)                   # End of Capturing Group (1)
