leftward

'not right' is the definition.
The definition suggests an adjective which matches the answer.

'abandoned hospital in a way' is the wordplay.
'abandoned' becomes 'left' (leave can mean to abandon).
'hospital in a way' becomes 'ward' (I can't justify this - if you can you should believe this answer much more).
'left'+'ward'='LEFTWARD'

'that's' acts as a link.

Can you help me to learn more?

(Another definition for leftward that I've seen is " not in right direction".)

I've seen this clue in the Sydney Morning Herald.
