Expensive honey (4)
I believe the answer is:
dear
I believe this clue is a double definition.
'expensive' is the first definition.
(similar in meaning)
'honey' is the second definition.
(I know that honey can be written as dear)
(Other definitions for dear that I've seen before include "Precious" , "close" , "address for partner" , "Costly (but loved!)" , "At a high cost" .)
