Translation of prose tale could make a bit of a bloomer (4,5)
I believe the answer is:
rose petal
'a bit of a bloomer' is the definition.
I can't judge whether this definition defines the answer.
'translation of prose tale could make' is the wordplay.
'translation of' indicates an anagram (I've seen this in other clues).
'could make' indicates an anagram.
'prose' anagrammed gives 'rosep'.
'tale' is an anagram of 'etal'.
'rosep'+'etal'='ROSE PETAL'
Can you help me to learn more?
(Other definitions for rose petal that I've seen before include "confetti perhaps" , "one's scented" .)
