Contraction "-'dn't" from formal English "would not"?

Question

Can "wouldn't" be reduced to the clitic **-'dn't** when attached to any other pronoun besides *y'all*, such as *she'dn't* or *you'dn't*? (Appearing for example in "*y'all'dn't've*" from formal English "you all would not have")

Answer 1

The only reason you may use this in writing is if you want to convey a particular dialect or accent for a character who is speaking. When just writing, you would need to write out wouldn't. In fact, using "would not" would be better than "wouldn't". You want to avoid using contractions when writing formal or professional communications.
