'allowed' is the definition.
(suffering is a kind of allowing)

'hurt by' is the wordplay.
'hurt' becomes 'suffer' (synonyms).
'by' becomes 'ed' (I can't justify this - if you can you should give a lot more credence to this answer).
'suffer'+'ed'='SUFFERED'

'to though one was' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?
