Founding Father William may end with distant objects and means of transport (5-9)
I believe the answer is:
penny-farthings
'founding father william' is the definition.
I don't know anything about this answer so I can't judge whether it can be defined by this definition.
'end with distant objects and means of transport' is the wordplay.
I cannot really see how this works, but
'end' could be 'thing' (thing is a kind of end) and 'thing' is found within the answer.
'distant' could be 'far' (synonyms) and 'far' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is present in the answer.
This explanation may well be incorrect...
'may' acts as a link.
Can you help me to learn more?
