Maybe led to rely unreasonably on the aged (7)
I believe the answer is:
elderly
'the aged' is the definition.
(I've seen this before)
'maybe led to rely' is the wordplay.
'maybe' is an anagram indicator.
'led'+'rely'='ledrely'
'ledrely' is an anagram of 'ELDERLY'.
'unreasonably on' acts as a link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for elderly that I've seen before include "... or not of tender years" , "Silver" , "Mature" , "Aged" , "Getting on a bit" .)
