Being stingy, orders inexpensive fish (10)
I believe the answer is:
cheapskate
'being' is the definition.
(cheapskate is a kind of being)
'inexpensive fish' is the wordplay.
'inexpensive' becomes 'cheap' (similar in meaning).
'fish' becomes 'skate' (skate is a kind of fish).
'cheap'+'skate'='CHEAPSKATE'
'stingy orders' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for cheapskate that I've seen before include "Miserly type" , "Mean person" , "ungenerous person" , "Mean type" , "Scrooge" .)
