Dice rolled in time set aside (8)
I believe the answer is:
dedicate
'set aside' is the definition.
'dedicate' can be an answer for 'set' (thesaurus). I am not certain of the 'aside' bit.
'dice rolled in time' is the wordplay.
'rolled' is an anagram indicator.
'in' is an insertion indicator.
'time' becomes 'date' (a date is a period of time).
'dice' anagrammed gives 'edic'.
'edic' inserted within 'date' is 'DEDICATE'.
Can you help me to learn more?
(Other definitions for dedicate that I've seen before include "Devote to a special purpose, say time or energy" , "Devote (to), pledge (to)" , "Devote to a sacred person or use" , "Address (eg, a book to a person)" , "Devote, address, to" .)
