Some treasure time to wander (5)
I believe the answer is:
trove
'some treasure' is the definition.
(trove is a kind of treasure)
'time to wander' is the wordplay.
'time' becomes 't' (abbreviation).
'to wander' becomes 'rove' ('rove' can be a synonym of 'wander').
't'+'rove'='TROVE'
(Other definitions for trove that I've seen before include "Store of treasures" , "Source of treasure" , "Hoard" , "Collection of valuables" , "Buried treasure" .)
