Qualified to be chosen
I believe the answer is:
eligible
'qualified to be chosen' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for eligible that I've seen before include "Satisfying the appropriate conditions" , "Available, qualifying" , "Qualified or fit as bachelor may be" , "Qualified to be chosen, say a bachelor" , "Regarded as desirable, say for marriage" .)
