Current bloom (6)
I believe the answer is:
flower
'current bloom' is the definition.
'flower' can be an answer for 'bloom' (synonyms). I'm unsure of the 'current' bit.
'current bloom' is the wordplay.
'current' becomes 'flow' (synonyms).
'bloom' becomes 'er' (I can't explain this - if you can you should believe this answer much more).
'flow'+'er'='FLOWER'
Can you help me to learn more?
(Other definitions for flower that I've seen before include "Bloom" , "One found in bed perhaps" , "rose, perhaps" , "Plant cultivated for blossoms" , "the best one can pick" .)
