I believe the answer is:

inane

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

'foolish' is the definition.
(inane can mean silly or foolish)

I cannot understand how the rest of the clue works.

(Other definitions for inane that I've seen before include "Devoid of intelligence" , "Delirious" , "Silly or senseless" , "Moronic" , "Empty-headed" .)

I've seen this clue in The Independent.
