Wicked romp, tale limited in time (8)
I believe the answer is:
temporal
'limited in time' is the definition.
The answer and definition are different parts of speech. However, adjectives and past participle verbs occasionally define each other.
'wicked romp tale' is the wordplay.
'wicked' indicates anagramming the letters.
'romp'+'tale'='romptale'
'romptale' with letters rearranged gives 'TEMPORAL'.
Can you help me to learn more?
(Other definitions for temporal that I've seen before include "Relating to time" , "Not eternal" , "profane" , "Secular; of the temples" , "Worldly, secular" .)
