'fit?' is the definition.
(I've seen this before)

I don't understand how the rest of the clue works.

(Other definitions for eligible that I've seen before include "Satisfying the appropriate conditions" , "Qualified to be chosen, say a bachelor" , "Regarded as desirable, say for marriage" , "Desirable as a spouse" , "Entitled, suitable" .)

I've seen this clue in The Sun.
