Virginia acted strangely and quit (7)
I believe the answer is:
vacated
'quit' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs can sometimes define each other.
'virginia acted strangely' is the wordplay.
'virginia' becomes 'va' (US state abbreviation).
'strangely' is an anagram indicator.
'acted' is an anagram of 'cated'.
'va'+'cated'='VACATED'
'and' acts as a link.
Can you help me to learn more?
(Another definition for vacated that I've seen is " Quitted".)
