On the sea, it turns up a lot in the southeast (5)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
spume
'on the sea it' is the definition.
I can't judge whether this definition defines the answer.
'turns up a lot in the southeast' is the wordplay.
'turns' is a reversal indicator.
'a lot' becomes 'm'.
'in the' indicates putting letters inside.
'southeast' becomes 'se' (synonyms).
'up' reversed gives 'pu'.
'pu'+'m'='pum'
'pum' placed inside 'se' is 'SPUME'.
Can you help me to learn more?
(Other definitions for spume that I've seen before include "Surf" , "Sea foam, froth" , "Froth on waves" , "Foam on waves" .)
