History of dad's old model car (4)
I believe the answer is:
past
'history' is the definition.
(I've seen this before)
'dad's old model car' is the wordplay.
I cannot quite understand how this works, but
'dad's' could be 'pas' (pa can mean someone's father) and 'pas' is found in the answer.
'model' could be 't' (Ford Model T car) and 't' is found within the answer.
No letters remain.
This explanation may well be incorrect...
'of' acts as a link.
Can you help me to learn more?
(Other definitions for past that I've seen before include "Beyond" , "The time that has elapsed" , "A person's earlier life history" , "Ended" , "Yesteryear" .)
