Provide finance for space on the US stock market (5)
I believe the answer is:
endow
'provide' is the definition.
(I've seen this in another clue)
'finance for space on the us stock market' is the wordplay.
I cannot really understand how this works, but
'space' could be 'en' (in printing, a space as wide as a letter 'n') and 'en' is present in the answer.
The remaining letters 'dow' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for endow that I've seen before include "Furnish, award" , "Woden (anag.)" , "Enrich (with a facility or gift)" , "Establish (university post) by giving funds" , "Give funding to establish (something)" .)
