Variety show that's disappointing group of stars reportedly (4)
I believe the answer is:
olio
'variety' is the definition.
(I've seen this before)
'of stars reportedly' is the wordplay.
'of' becomes 'o''.
'stars' becomes 'Leo' (constellation).
'reportedly' indicates a 'sounds like' (homophone) clue.
'o'+'leo'='oleo'
'oleo' is a homophone of 'OLIO'.
'show that's disappointing group' acts as a link.
This may not be right. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for olio that I've seen before include "Collection of miscellany" , "Variety" , "Savoury dish of different types of meat and vegetable" , "Mixture" .)
