Modifiers transposing late tirades (9)

I believe the answer is:

alterants

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

'modifiers' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'transposing late tirades' is the wordplay.
'transposing' indicates an anagram (I've seen 'transposed' mean this).
'tirades' becomes 'rants' (I've seen this in another clue).
'late' is an anagram of 'alte'.
'alte'+'rants'='ALTERANTS'

Can you help me to learn more?
