Eat around six? Perfect! (6)
I believe the answer is:
divine
'perfect' is the definition.
(thesaurus)
'eat around six?' is the wordplay.
'eat' becomes 'dine' (to dine is to eat a meal).
'around' indicates putting letters inside.
'six?' becomes 'VI' (Roman numerals).
'dine' placed around 'vi' is 'DIVINE'.
(Other definitions for divine that I've seen before include "Of or coming from God" , "Godly or celestial" , "Search for water with a rod" , "Emanating from God" , "Theologian" .)
