I'm a little stuck... Click here to teach me more about this clue!

'salvaged from this?' is the definition.
The definition suggests a singular noun which matches the answer.

'keg a crew possibly' is the wordplay.
'possibly' indicates anagramming the letters.
'keg'+'a'+'crew'='kegacrew'
'kegacrew' with letters rearranged gives 'WRECKAGE'.

Can you help me to learn more?

(Other definitions for wreckage that I've seen before include "Ruined remains" , "Sign of misfortune at sea" , "Remains of destruction" , "Debris" , "Ruin" .)
