Pleased to hold contract (5)
I believe the answer is:
lease
'contract' is the definition.
(I know that lease is a type of contract)
'pleased to hold' is the wordplay.
'to hold' indicates the answer is hidden within the clue (I've seen 'holding' mean this).
'LEASE' is hidden within 'pleased'.
(Other definitions for lease that I've seen before include "Tenancy contract" , "Rent (a property)" , "Contract allowing use of a property" , "Renting contract" , "From legal document" .)
