Caught insect soaring around league star (5)
I believe the answer is:
celeb
'star' is the definition.
(I've seen this in another clue)
'caught insect soaring around league' is the wordplay.
'caught' becomes 'c' (cricket abbreviation).
'insect' becomes 'bee' (bee is a type of insect).
'soaring' shows that the letters should be reversed in order (in a down clue, letters 'soar' up).
'around' indicates putting letters inside.
'league' becomes 'l' (abbreviation).
'bee' reversed gives 'eeb'.
'eeb' going around 'l' is 'eleb'.
'c'+'eleb'='CELEB'
(Other definitions for celeb that I've seen before include ""Personality"" , "Household name" , "Famous person (colloq.)" , "Prominent figure" , "Big name" .)
