Eastern bird coming to a lake, not stopping (7)
I believe the answer is:
eternal
'not stopping' is the definition.
(I've seen this before)
'eastern bird coming to a lake' is the wordplay.
'eastern' becomes 'e'.
'bird' becomes 'tern' (tern is a kind of bird**).
'coming to' is a charade indicator (letters next to each other).
'lake' becomes 'l'.
'e'+'tern'+'a'+'l'='ETERNAL'
(Other definitions for eternal that I've seen before include "carrying on endlessly" , "Immortal" , "Timeless" , "Perpetual" , "Forever or unchanging" .)
