'screw' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'undone ergo almost out' is the wordplay.
'almost' means to remove the last letter (most of the word but not all of it).
'out' indicates an anagram (out can mean wrong or inaccurate).
'undone'+'ergo'='undoneergo'
'undoneergo' with its last letter taken off is 'undoneerg'.
'undoneerg' with letters rearranged gives 'DUNGEONER'.
