Information from knight at present on shelf (9)
I believe the answer is:
knowledge
'information' is the definition.
(thesaurus)
'knight at present on shelf' is the wordplay.
'knight' becomes 'k'.
'at present' becomes 'now' ('now' can be a synonym of 'at present').
'on' says to put letters next to each other.
'shelf' becomes 'ledge' ('ledge' can be a synonym of 'shelf').
'k'+'now'+'ledge'='KNOWLEDGE'
'from' acts as a link.
(Other definitions for knowledge that I've seen before include "practical skill" , "Info" , "Erudition - ability" , "Information gained through experience" , "a small amount is risky" .)
