Like a broader smile from son that is held in acclaim (8)

Ross

I believe the answer is:

cheesier

'like a broader smile' is the definition.

'son that is held in acclaim' is the wordplay.
'son' becomes 's'.
'that is' becomes 'ie' ('i.e.' can be a synonym of 'that is').
'held in' is an insertion indicator.
'acclaim' becomes 'cheer' (I've seen this before**).
's'+'ie'='sie'
'sie' going inside 'cheer' is 'CHEESIER'.

'from' is the link.

I've seen this clue in The Guardian.
