Submerged position of cedilla say (8)
I believe the answer is:
undersea
'submerged position of cedilla say' is the definition.
'undersea' can be an answer for 'submerged' (I've seen this before). I'm not certain of the 'position of cedilla say' bit.
'submerged position of cedilla say' is the wordplay.
'submerged' becomes 'under'.
'position of cedilla say' becomes 'sea' (I can't explain this - if you can you should believe this answer much more).
'under'+'sea'='UNDERSEA'
Can you help me to learn more?
(Other definitions for undersea that I've seen before include "submerged" , "Beneath the surface of the ocean" , "Beneath the oceans" , "in salt water" , "Submarine" .)
