Drive away duck circling one small lake (8)
I believe the answer is:
dislodge
'drive away' is the definition.
(I've seen this before)
'duck circling one small lake' is the wordplay.
'duck' becomes 'dodge' (synonyms).
'circling' means one lot of letters goes inside another (circling can mean going around or containing).
'one' becomes 'i' (Roman numeral).
'small' becomes 's' (abbreviation - e.g. clothes size).
'lake' becomes 'L' (geographical abbreviation).
'i'+'s'+'l'='isl'
'dodge' enclosing 'isl' is 'DISLODGE'.
(Other definitions for dislodge that I've seen before include "Shift" , "Knock out of a fixed position" , "put out" , "Move from a fixed position" , "Force from an established position" .)
