Edible mollusc from the east in Italian soup (5)
I believe the answer is:
snail
'edible mollusc' is the definition.
'snail' can be an answer for 'mollusc' (snail is a kind of mollusc). I'm not sure about the 'edible' bit.
'from the east in italian soup' is the wordplay.
'from the east' shows that the letters should be reversed in order (on a map from right to left).
'in' indicates a hidden word.
'lians' is hidden in the letters of 'italian soup'.
'lians' reversed gives 'SNAIL'.
Can you help me to learn more?
(Other definitions for snail that I've seen before include "Crawler whose home has a helix pattern" , "Escargot" , "Not one of the fleet" , "Sluggish person - kind of mail" , "Slow slithery animal" .)
