Moving here, a tourist finally can be warm again (6)
I believe the answer is:
reheat
'be warm again' is the definition.
(I've seen this before)
'moving here a tourist finally' is the wordplay.
'moving' indicates anagramming the letters.
'finally' suggests the final letters.
The last letter of 'tourist' is 't'.
'here' anagrammed gives 'rehe'.
'rehe'+'a'+'t'='REHEAT'
'can' acts as a link.
(Other definitions for reheat that I've seen before include "Of cooked food, give another go in the microwave" , "Method of getting extra power from jet engine" , "Bring back to the boil, for instance" , "Warm (food) up again" , "Cook again" .)
