Hire daily, for a limited period (7)
I believe the answer is:
charter
'hire' is the definition.
(synonyms)
'daily for a limited period' is the wordplay.
'daily' becomes 'char' (I've seen this before).
'for a limited period' becomes 'ter' (I am not sure about this - if you are sure you should believe this answer much more).
'char'+'ter'='CHARTER'
Can you help me to learn more?
(Other definitions for charter that I've seen before include "Let or hire a ship or aircraft" , "Hire - document granting privileges" , "Written constitution" , "Hire a boat or aircraft" , "Hire (of aircraft/ship)" .)
