Time for tablet to be found in sack? (7)
I believe the answer is:
pillage
'sack?' is the definition.
(I've seen this in another clue)
'time for tablet' is the wordplay.
'time' becomes 'age' (an age is a period of time).
'for' means one lot of letters go next to another (I've seen this in other clues).
'tablet' becomes 'pill' (synonyms).
'age' put after 'pill' is 'PILLAGE'.
'to be found in' is the link.
(Other definitions for pillage that I've seen before include "Rob with violence" , "Loot" , "Plunder, sack" , "Sacking" , "Violent stealing" .)
