Which person told dad, around 50 to fuss? (6)
I believe the answer is:
hoopla
'fuss?' is the definition.
(I've seen this before)
'which person told dad around 50' is the wordplay.
'which person' becomes 'who' (I've seen this before).
'told' indicates a 'sounds like' (homophone) clue.
'dad' becomes 'pa' (synonyms).
'around' indicates putting letters inside.
'50' becomes 'l' (Roman numeral).
'who' is a homophone of 'hoo'.
'pa' enclosing 'l' is 'pla'.
'hoo'+'pla'='HOOPLA'
'to' acts as a link.
(Other definitions for hoopla that I've seen before include "Throwing event at a fair" , "fair prize at this" , "game in which all-round achievement is rewarded" , "Fairground throwing game" , "Throwing game where prizes aimed for" .)
