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

'bless you' is the definition.
I can't tell whether this defines the answer.

'different guides then' is the wordplay.
'different' is an anagram indicator (letters placed in a different order).
'guides'+'then'='guidesthen'
'guidesthen' is an anagram of 'GESUNDHEIT'.

Can you help me to learn more?
