Maiden from Bude warped time (5)
I believe the answer is:
debut
'maiden' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'bude warped time' is the wordplay.
'warped' is an anagram indicator.
'time' becomes 't' (abbreviation).
'bude' anagrammed gives 'debu'.
'debu'+'t'='DEBUT'
'from' acts as a link.
Can you help me to learn more?
(Other definitions for debut that I've seen before include "opening" , "First public appearance of performer" , "First appearance, a coming-out" , "entrance" , "Aurora" .)
