Ran up with Penny's aromatic oil (4)
I believe the answer is:
nard
'aromatic oil' is the definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'ran up with penny's' is the wordplay.
'up with' indicates an anagram (letters get chucked up).
'penny' becomes 'd' (abbreviation e.g. Lsd - pounds, shillings, pence).
'ran' anagrammed with 'd' makes 'NARD'.
Can you help me to learn more?
(Other definitions for nard that I've seen before include "Plant yielding aromatic balsam" , "Aromatic plant once used in medicines" , "ointment" .)
