Time to restore confidence to a son missing love? (8)
I believe the answer is:
treasure
'love?' is the definition.
(treasuring is a kind of loving)
'time to restore confidence to a son missing' is the wordplay.
'time' becomes 't'.
'to restore confidence' becomes 'reassure' (I've seen this before).
'to a son' becomes 's'.
'missing' suggests deleting specific letters.
'reassure' with 's' taken out is 'reasure'.
't'+'reasure'='TREASURE'
(Other definitions for treasure that I've seen before include "Valuables, fortune" , "Valued possession, buried perhaps" , "Accumulated riches" , "quantity of wealth" , "See 10" .)
