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

'noted after acts of rewording?' is the definition.
I can't judge whether this defines the answer.

'unusual tonal strains' is the wordplay.
'unusual' indicates an anagram.
'tonal'+'strains'='tonalstrains'
'tonalstrains' is an anagram of 'TRANSLATIONS'.

Can you help me to learn more?
