Short post from poet circling round lakes (7)
I believe the answer is:
bollard
'short post' is the definition.
'bollard' can be an answer for 'post' (I have seen 'Strong post' mean 'bollard' so perhaps 'post' could also mean 'bollard'). I'm not certain of the 'short' bit.
'poet circling round lakes' is the wordplay.
'poet' becomes 'bard' (bard is a kind of poet).
'circling' means one lot of letters goes inside another (circling can mean going around or containing).
'round' becomes 'o' (o is a circular letter).
'lakes' becomes 'LL' (a geographical abbreviation for lake written twice).
'o'+'ll'='oll'
'bard' enclosing 'oll' is 'BOLLARD'.
'from' is the link.
Can you help me to learn more?
(Other definitions for bollard that I've seen before include "Mooring post - traffic restriction device" , "Roadside post" , "Strong post" , "Short post barring traffic" , "Thick post for mooring" .)
