Be able to give half a loaf to Harrison, say (6)
I believe the answer is:
afford
'harrison say' is the definition.
Although both the answer and definition are verbs in their base form, I can't understand how one could define the other.
'be able to give half a loaf to' is the wordplay.
'be able' becomes 'd' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'to' says to put letters next to each other (I've seen this in other clues).
'give' is a charade indicator (letters next to each other).
'half a' means to take half the letters.
'to' becomes 'for'.
'loaf' with half the letters taken is 'af'.
'af' next to 'for' is 'affor'.
'd' put after 'affor' is 'AFFORD'.
Can you help me to learn more?
(Other definitions for afford that I've seen before include "Have the means to pay" , "Have enough money to pay for" , "Provide (an opportunity)" , "Give, provide" , "Be able to buy" .)
