Just found out that LT flags error for words such as doin',lil',goin', etc. Wanted to know how to add these words as exceptions. With a little research, I found that I need to modify disambiguation.xml
<rule name="Words ending with '" id="APOSTROPHE_ENDING">
I tried using regular expression
[a-z]+' for such words, but this doesn't work. Can some please point out the mistake. Thank you in advance.
