Undying Latin verse recollecting gods primarily (11)
I believe the answer is:
everlasting
'undying' is the definition.
(I've seen this before)
'latin verse recollecting gods primarily' is the wordplay.
'recollecting' indicates anagramming the letters.
'primarily' suggests taking the first letters.
The initial letter of 'gods' is 'g'.
'latin'+'verse'='latinverse'
'latinverse' anagrammed gives 'everlastin'.
'everlastin'+'g'='EVERLASTING'
(Other definitions for everlasting that I've seen before include "describes Wonka's gobstoppers" , "Eternal" , "Unceasing" , "Timeless" , "description of the rest Romeo set up here?" .)
