Unshod, poor explorer of North America (6)
I believe the answer is:
hudson
'explorer of north america' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'unshod poor' is the wordplay.
'poor' is an anagram indicator.
'unshod' is an anagram of 'HUDSON'.
Can you help me to learn more?
(Other definitions for hudson that I've seen before include "New York river; Upstairs/ Downstairs butler" , "River in New York city" , "NY river; Canadian Bay" , "ROCK] a > banker" , "Large bay in Canada" .)
