Channel's only occupant is a naval hero (6)
I believe the answer is:
nelson
'a naval hero' is the definition.
(I've seen this before)
'channel's only occupant' is the wordplay.
'NELSON' is hidden in amongst the letters.
However, I'm not sure how this is indicated.
'is' acts as a link.
Can you help me to learn more?
(Other definitions for nelson that I've seen before include "Sailor" , "Naval hero, d. 21 October 1805" , "Admiral; wrestling hold" , "Lady Hamilton's navy lover" , "British admiral, d. 1805" .)
