End with trick and hint this will involve old penny (8)
I believe the answer is:
conclude
'end' is the definition.
(I know that conclude is a more specific form of end)
'trick and hint this will involve old penny' is the wordplay.
'trick' becomes 'con' (a con is a fraud or trick).
'and' is a charade indicator (letters next to each other).
'hint this will' becomes 'clue' (I can't justify this - if you can you should believe this answer much more).
'involve' is an insertion indicator.
'old penny' becomes 'd' (pre-decimal abbreviation for penny).
'clue' placed around 'd' is 'clude'.
'con'+'clude'='CONCLUDE'
'with' is the link.
Can you help me to learn more?
(Other definitions for conclude that I've seen before include "Close, end" , "Decide by reasoning or draw to a close" , "Bring to a close" , "Wind up" , "Finish - deduce" .)
