More aged (5)
(Other definitions for elder that I've seen before include "Bush" , "Kind of tree or senior person in tribe" , "Senior member of a tribe" , "Layman of the church" , "First-born" .)
'more aged' is the definition.
('old' can be similar in meaning to 'aged')
This is the entire clue.
(Other definitions for older that I've seen before include "Elder" , "Of greater age (O, not E)" , "More ancient" , "Advanced in years (but wiser?)" , "Less young" .)
