One dabbled, capriciously, and improvised (8)
I believe the answer is:
adlibbed
'improvised' is the definition.
Both the definition and answer are past participle verbs.
Maybe there's a link between them I don't understand?
'one dabbled capriciously' is the wordplay.
'one' becomes 'i' (Roman numeral).
'capriciously' indicates an anagram.
'i'+'dabbled'='idabbled'
'idabbled' is an anagram of 'ADLIBBED'.
'and' acts as a link.
Can you help me to learn more?
(Another definition for adlibbed that I've seen is " improvised words?".)
