chaperon

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

'guard' is the definition.
(thesaurus)

'man confusing nero' is the wordplay.
'man' becomes 'chap' (I've seen this in other clues**).
'confusing' indicates an anagram.
'nero' with letters rearranged gives 'eron'.
'chap'+'eron'='CHAPERON'

'of honour perhaps for' is the link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for chaperon that I've seen before include "Girl minder from Cape Horn" , "Guardian" , "Preach on about older woman in charge of girl" , "Escort" , "Woman supervising girl" .)

I've seen this clue in the Irish Times and the Irish Times (Crosaire).
