Father of Juliet and maybe Paul, etc. (7)
'father of juliet' is the definition.
The definition suggests a singular noun which matches the answer.
'maybe paul etc' is the wordplay.
'maybe' indicates an anagram.
'pauletc' is an anagram of 'CAPULET'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for capulet that I've seen before include "Verona family", "Shakespeare's Juliet's family name", "Juliet's house", "Family in play", "Veronese family name".)
