'monster?' is the definition.
(fairy tale monster)

'hesitating turn back' is the wordplay.
'hesitating' becomes 'er'.
'turn' becomes 'go' (a person's move in a board game).
'back' is a reversal indicator.
'er'+'go'='ergo'
'ergo' backwards is 'OGRE'.

'i'm' acts as a link.
This may not be correct. It may belong to another bit of the clue.

Can you help me to learn more?
