Running behind after pressure in horse race (5)
I believe the answer is:
plate
'horse race' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'running behind after pressure' is the wordplay.
'running behind' becomes 'late' (I've seen this before).
'after' means one lot of letters go next to another.
'pressure' becomes 'p' (scientific abbreviation).
'late' after 'p' is 'PLATE'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for plate that I've seen before include "South American river" , "Flat dish for food" , "that batter will stand on" , "Coat with metal" , "Item of crockery" .)
