Is it ever acceptable to use a semicolon in place of an apostrophe?
Seems the question is incomplete!
However, I will answer it by sporting mind.
What do know you about a semi colon like ;
Or what do you know about an apostrophe? '
Semicolon is one of punctuation signs that are ended of a depended or an independent clause to start an independent clause.
I wonder; what was the real question was it?
Apostrophe is a different issue, like it indicates a possession meaning.
The cat licks its paws.
Do you notice it?
Now, your question is like that:
Those are the doctors rooms'; sorry, they are busy now!
Bobby's room is cleaner than Smith's; I am known it.
No, not possible, seems.
