Might it deter free camping? (7)
I believe the answer is:
trident
'might it deter' is the definition.
I can't tell whether this defines the answer.
'free camping?' is the wordplay.
I cannot really understand how this works, but
'free' could be 'rid' (to be free of something is to be rid of it) and 'rid' is located in the answer.
'camping?' could be 'tent' (I've seen this in other clues) and 'tent' is found within the leftover letters.
No letters remain.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for trident that I've seen before include "spear carried at sea" , "Three-pronged weapon" , "Neptune's spear - missile" , "Neptune's or Britannia's spear" , "Spear held by Neptune or Britannia" .)
