Hi,
Im an unsure whter I should go with a comma here or a semi-colon?
"Mary Warren was too scared to testify against Abigail Williams(,)(![Wink <img src=]()
" src="/emoticons/emotion-5.gif"> thus more concerned about herself than the numerous innocent people who are wrongly accused."
I'm thinking the comma. Yes. A semi-colon would be incorrect, because what would follow it would not be in a form that could be an independent sentence. In other words, the second part is just an adjectival phrase.
I would say 'were . . . accused' rather than 'are . . accused'.
If I wanted to write very carefully, I'd put 'and ' before 'thus'.
Best wishes, Clive
