Went through water, parking in boggy area (5)
I believe the answer is:
swamp
'boggy area' is the definition.
(I've seen this before)
'went through water parking' is the wordplay.
'went' becomes 'swam' (swimming is a kind of going).
'through water parking' becomes 'p' (I can't justify this - if you can you should give a lot more credence to this answer).
'swam'+'p'='SWAMP'
'in' acts as a link.
Can you help me to learn more?
(Other definitions for swamp that I've seen before include "Bog; inundate" , "Bog, marsh" , "marshy tract" , "In flood" , "Boggy ground" .)
