Clean bottom lip following medic (6)
I believe the answer is:
dredge
'clean bottom' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'lip following medic' is the wordplay.
'lip' becomes 'edge' (I've seen this in another clue).
'following' is a charade indicator (letters next to each other).
'medic' becomes 'dr' (doctor).
'edge' put after 'dr' is 'DREDGE'.
Can you help me to learn more?
(Other definitions for dredge that I've seen before include "Clear a channel" , "(Of harbour or river) make deeper" , "Clear river bottom" , "Clear (riverbed)" , "Scour (riverbed); sprinkle with sugar" .)
