Terrace rearranged by company providing canapés etc (7)
I believe the answer is:
caterer
'company providing canapes etc' is the definition.
I can't tell whether this defines the answer.
'terrace rearranged' is the wordplay.
'rearranged' indicates anagramming the letters.
'terrace' anagrammed gives 'CATERER'.
'by' is the link.
Can you help me to learn more?
(Other definitions for caterer that I've seen before include "Food and drink supplier" , "Terrace (anag.)" , "Person who supplies food for social events" , "Someone who provides food and service" , "Someone needed for party" .)
