Channel so nearly consumes seafaring lord (6)
I believe the answer is:
nelson
'seafaring lord' is the definition.
The definition suggests a singular noun which matches the answer.
'channel so nearly consumes' is the wordplay.
'consumes' indicates the answer is hidden within the clue (the answer has been consumed by the clue).
'NELSON' is hidden within 'channel so nearly'.
Can you help me to learn more?
(Other definitions for nelson that I've seen before include "'England expects' admiral" , "English naval hero" , "British admiral, d. 1805" , "Lady Hamilton's naval lover" , "Admiral; wrestling hold" .)
