Drag bed from unsightly spot over by lake (5)
I believe the answer is:
trawl
'drag' is the definition.
(I've seen this before)
'bed from unsightly spot over by lake' is the wordplay.
'bed from unsightly spot' becomes 'wart' (I can't justify this - if you can you should believe this answer much more).
'over' says the letters should be written in reverse.
'by' is a charade indicator (letters next to each other).
'lake' becomes 'L' (geographical abbreviation).
'wart' in reverse letter order is 'traw'.
'traw'+'l'='TRAWL'
Can you help me to learn more?
(Other definitions for trawl that I've seen before include "Fishing dragnet" , "Fish using nets" , "Net dragged behind fishing boats" , "Long fishing line with many shorter lines and hooks" , "Fish by dragging bag-net along sea bed" .)
