Thinking the world of a party call (7)
I believe the answer is:
adoring
'thinking the world' is the definition.
Although both the answer and definition are present participle verbs, I can't see how they can define each other.
'a party call' is the wordplay.
'party' becomes 'do' (do is a kind of party).
'call' becomes 'ring' (telephone call).
'a'+'do'+'ring'='ADORING'
'of' is the link.
Can you help me to learn more?
(Other definitions for adoring that I've seen before include "Loving deeply" , "Extravagantly indulgent" , "Very keen on" , "Being very fond of" , "Worshipful" .)
