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

'early learning' is the definition.
The definition suggests a singular noun which matches the answer.

'iron giant title ruined' is the wordplay.
'ruined' indicates an anagram.
'iron'+'giant'+'title'='irongianttitle'
'irongianttitle' with letters rearranged gives 'TOILET-TRAINING'.

'for' acts as a link.

Can you help me to learn more?

(Another definition for toilet training that I've seen is " Infant practice".)
