pointedly

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

'in a cutting way' is the definition.
I can't judge whether this definition defines the answer.

'turned tepid only' is the wordplay.
'turned' indicates anagramming the letters.
'tepid'+'only'='tepidonly'
'tepidonly' anagrammed gives 'POINTEDLY'.

Can you help me to learn more?
