Bear out a keg is splintered: there's damage (8)
I believe the answer is:
breakage
'damage' is the definition.
(I've seen this before)
'bear out a keg is splintered' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'is splintered' indicates anagramming the letters.
'bear' is an anagram of 'brea'.
'a'+'keg'='akeg'
'akeg' is an anagram of 'kage'.
'brea'+'kage'='BREAKAGE'
'there's' acts as a link.
(Other definitions for breakage that I've seen before include "Fracture" , "Reimbursement for goods damaged in transit" , "Smashed article" , "Act of smashing" , "Something smashed" .)
