Accommodating bore with extremely high rental (5,2,6)
I believe the answer is:
eager to please
'accommodating' is the definition.
(someone accommodating is eager to please)
'bore with extremely high rental' is the wordplay.
'bore' becomes 'eager' (eager is a kind of bore).
'with' means one lot of letters go next to another.
'extremely high' becomes 'top' (associated in meaning. I am not sure about the 'extremely' bit.).
'rental' becomes 'lease' (synonyms).
'eager'+'top'+'lease'='EAGER TO PLEASE'
Can you help me to learn more?
(Another definition for eager to please that I've seen is " Obliging".)
