Beloved costing a lot of money (4)
I believe the answer is:
dear
'beloved' is the definition.
(I know that beloved can be written as dear)
'costing a lot of money' is the wordplay.
I cannot really see how this works, but
'a' is present in the answer.
'lot' could be 'd' and 'd' is found within the answer.
The remaining letters 'er' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dear that I've seen before include "Precious" , "Beloved - expensive" , "Baby" , "pet > ducks" , "Expensive -- honey" .)
