Daisy's over getting cross with peeper (5)
I believe the answer is:
oxeye
'daisy's' is the definition.
(I've seen this before)
'over getting cross with peeper' is the wordplay.
'over' becomes 'o' (cricket abbreviation).
'getting' means one lot of letters go next to another.
'cross with' becomes 'x' (I am not sure about the 'with' bit.**).
'peeper' becomes 'eye' ('eye' can be a synonym of 'peeper').
'o'+'x'+'eye'='OXEYE'
Can you help me to learn more?
(Other definitions for oxeye that I've seen before include "Flowering herb" , "Wild daisy" , "Variety of daisy" , "Wild chrysanthemum" , "Daisy-like flower" .)
