History is made in Pennsylvania Street (4)
I believe the answer is:
past
'history' is the definition.
(I've seen this in another clue)
'pennsylvania street' is the wordplay.
'pennsylvania' becomes 'PA'.
'street' becomes 'st' (abbreviation).
'pa'+'st'='PAST'
'is made in' 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 past that I've seen before include "Yesteryear" , "A person's earlier life history" , "tense" , "The time that has elapsed" , "over and done with" .)
