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

'forces one to feel it isn't silly' is the definition.
I can't judge whether this defines the answer.

'forces one to feel' is the wordplay.
'forces' becomes 'makes' (I've seen this in another clue).
'one to feel' becomes 'sense' (I've seen this in another clue).
'makes'+'sense'='MAKES SENSE'

Can you help me to learn more?

I've seen this clue in the Evening Standard.
