Not very exciting for one who lacks drive (10)
I believe the answer is:
pedestrian
This clue could be a double definition.
'not very exciting for' is the first definition.
The definition suggests a singular noun which matches the answer.
'one who lacks drive' is the second definition.
The answer is a person as well as being a singular noun. This is suggested by the definition.
Can you help me to learn more?
(Other definitions for pedestrian that I've seen before include "wearer of leather?" , "not very fast" , "Boring" , "lacking inspiration" , "Dull; walker" .)
