Desirable, sought-after (8)
I believe the answer is:
enviable
I believe this is a double definition.
'desirable' is the first definition.
(similar in meaning)
'sought-after' is the second definition.
(I've seen this before)
(Other definitions for enviable that I've seen before include "Be venial - it makes others jealous" , "Desirable enough to make one green-eyed" , "Likely to cause jealousy" , "sought-after" , "Much to be desired" .)
