hypersensitive

I'm a little stuck... Click here to teach me more about this clue!

'prone to overreact?' is the definition.
I can't judge whether this definition defines the answer.

'priest i envy he's awfully' is the wordplay.
'awfully' indicates an anagram.
'priest'+'i'+'envy'+'hes'='priestienvyhes'
'priestienvyhes' anagrammed gives 'HYPERSENSITIVE'.

Can you help me to learn more?

(Another definition for hypersensitive that I've seen is " Abnormally quick to react".)

I've seen this clue in The Times.
