Go on past Los Angeles and you'll find it very wet (6)
I believe the answer is:
lagoon
'you'll find it very wet' is the definition.
I can't tell whether this definition defines the answer.
'go on past los angeles' is the wordplay.
'past' says to put letters next to each other.
'los angeles' becomes 'LA' (abbreviation).
'go'+'on'='goon'
'goon' put after 'la' is 'LAGOON'.
'and' is the link.
Can you help me to learn more?
(Other definitions for lagoon that I've seen before include "Pool" , "Body of salt water cut off from the sea" , "Inland sea" , "Shallow seaside lake" , "Lake inside coral reef" .)
