Give an address for a test sample (5)
I believe the answer is:
orate
'give an address' is the definition.
(I've seen this in another clue)
'for a test sample' is the wordplay.
'sample' indicates a hidden word (I've seen 'sampled' mean this (I've seen this in other clues)).
'ORATE' can be found hidden inside 'for a test'.
(Other definitions for orate that I've seen before include "Speak formally" , "Speechify" , "Pontificate" , "Speaker may" , "Give speech" .)
