Bloomer turning up in corduroys I admit (5)
I believe the answer is:
daisy
'bloomer' is the definition.
(I know that daisy is a type of bloomer)
'turning up in corduroys i admit' is the wordplay.
'turning up' shows that the letters should be reversed in order.
'in' indicates a hidden word.
'ysiad' can be found hidden inside 'corduroys i admit'.
'ysiad' in reverse letter order is 'DAISY'.
(Other definitions for daisy that I've seen before include "See 1 Across" , "Old song: '. . . . ., . . . . . give me your answer, do'" , "girl" , "Composite" , "Common plant" .)
