Reeked of fish (5)
I believe the answer is:
smelt
This could be a double definition.
'reeked' is the first definition.
The answer and definition can be both to do with perception as well as being past participle verbs.
Maybe you can see a link between them that I can't see?
'fish' is the second definition.
(smelt is a kind of fish)
'of' is the link.
Can you help me to learn more?
(Other definitions for smelt that I've seen before include "were high" , "Savoured" , "Inhaled odour" , "was whiffy" , "Food fish often fried" .)
