Ages to mend a broken nose
I believe the answer is:
eons
'ages' is the definition.
(I know this)
'mend a broken nose' is the wordplay.
'nose' anagrams to 'EONS'.
Though, I am not clear how this is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for eons that I've seen before include "Years and years" , "Nose (anag)" , "Vast ages" , "Divisions of archaeological time" , "Long periods of time - noes have it" .)
