Savoy perhaps putting luggage item in taxi with energy (7)
I believe the answer is:
cabbage
'savoy' is the definition.
(I've seen this before)
'item in taxi with energy' is the wordplay.
'item' becomes 'bag' (I have seen 'Item of luggage ' mean 'bag' so perhaps 'item' could also mean 'bag').
'in' means one lot of letters goes inside another.
'taxi' becomes 'cab' (synonyms).
'with' is a charade indicator (letters next to each other).
'energy' becomes 'e' (physics symbol as in E=mca).
'cab'+'e'='cabe'
'bag' going within 'cabe' is 'CABBAGE'.
'perhaps putting luggage' is the link.
I am not very happy about this link. Some or all of it may be part of another bit of the clue.
(Other definitions for cabbage that I've seen before include "Savoy vegetable" , "Beg a cab for the strange vegetable" , "Variety of brassica" , "Vegetable with dense head of leaves" , "Leafy vegetable" .)
