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

'realised truth' is the definition.
The definition suggests a past participle verb which matches the answer.

'proverb when finished' is the wordplay.
'proverb' becomes 'saw' (synonyms).
'when finished' becomes 'through' (similar in meaning. I am not sure about the 'when' bit.).
'saw'+'through'='SAW THROUGH'

'of' is the link.
