Online businesswoman Dorothy picked up butterfly (9)
I believe the answer is:
dotcommer
'butterfly' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.
'online businesswoman dorothy' is the wordplay.
I cannot really see how this works, but
'online' could be 'e' (abbreviation for electronic, e.g. in ecommerce) and 'e' is present in the answer.
'dorothy' could be 'dot' (nickname for someone called Dorothy) and 'dot' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'picked up' is the link.
Can you help me to learn more?
(Other definitions for dotcommer that I've seen before include "E-businessperson" , "Online dealer" .)
