State the name on the house (5)
I believe the answer is:
idaho
'state' is the definition.
(Idaho is an example)
'the name on the house' is the wordplay.
'the name' becomes 'ida' (**).
'on' means one lot of letters go next to another.
'the house' becomes 'ho' (abbreviation for house).
'ida'+'ho'='IDAHO'
(Other definitions for idaho that I've seen before include "part of US near Washington" , "American state, capital Boise (5)" , "Rocky Mountain state" , "US state E. of Oregon" , "Pertaining to the Bard" .)
