Badly hoarse when on dry land (6)
I believe the answer is:
ashore
'on dry land' is the definition.
(I've seen this before)
'badly hoarse' is the wordplay.
'badly' indicates an anagram.
'hoarse' anagrammed gives 'ASHORE'.
'when' acts as a link.
(Other definitions for ashore that I've seen before include "Beached" , "beach" , "On land (as opposed to the sea)" , "Going on land from sea" , "Hoarse (anag)" .)
