Indicate agreement with father, on reflection when it comes to device accessory (3-2)
I believe the answer is:
add-on
'accessory' is the definition.
(I've seen this in another clue)
'indicate agreement with father on reflection' is the wordplay.
'indicate agreement' becomes 'nod' (I've seen this before).
'with' is a charade indicator (letters next to each other).
'father' becomes 'da' (da can mean dad).
'on reflection' shows that the letters should be reversed in order.
'nod'+'da'='nodda'
'nodda' written backwards gives 'ADD-ON'.
'when it comes to device' is the link.
I am not very happy about this link. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for add-on that I've seen before include "Extra charge" , "Feature supplementing standard model" , "Computer optional extra" , "Optional item as supplement or increment" , "Computer peripheral" .)
