This woman's minibus gets energy from spinning donkey (7)
I believe the answer is:
vanessa
'this woman's' is the definition.
'minibus gets energy from spinning donkey' is the wordplay.
'minibus' becomes 'van' (I've seen this in another clue).
'gets energy' becomes 'e' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'from' says to put letters next to each other.
'spinning' is a reversal indicator.
'donkey' becomes 'ass' (ass is a term for a donkey).
'ass' in reverse letter order is 'ssa'.
'van'+'e'+'ssa'='VANESSA'
Can you help me to learn more?
(Other definitions for vanessa that I've seen before include "Girl's name - butterfly genus" , "Girl's name; red admiral, painted lady genus" , "Red admiral butterfly" .)
