What complicated completion of house sale? (5)
I believe the answer is:
lease
'what complicated completion of house sale?' is the definition.
I can't judge whether this definition defines the answer.
'complicated completion of house sale?' is the wordplay.
'complicated' is an anagram indicator (a complex or confusing ordering of the letters).
'completion of' says to take the final letters.
The last letter of 'house' is 'e'.
'e'+'sale'='esale'
'esale' is an anagram of 'LEASE'.
Can you help me to learn more?
(Other definitions for lease that I've seen before include "Tenancy contract" , "Let; rent" , "Contract for, say, use of building" , "Contract for use of land or building" , "Letting contract" .)
