Over-sensitive to criticism

Hello everyone.

Would anyone please explain to me what is the meaning of this phrase ‘over-sensitive to criticism’.

Thanks in advance.

.
reacts too strongly to being criticized
.

I would have written “overly sensitive” – am I being overly adverbial?

.
I’d choose either overly sensitive or the unhyphenated oversensitive. :smiley:

Thank you so much Mister Micawber for answering my question.
