Maroons a musical group on first of September (8)
I believe the answer is:
abandons
'maroons' is the definition.
The definition and answer can be both to do with ownership as well as being verbs in their -s form.
Perhaps they are linked in a way I don't understand?
'a musical group on first of september' is the wordplay.
'musical group' becomes 'band' (band is a kind of musical group).
'first of september' becomes 's' (1st letter of 'september').
'a'+'band'+'on'+'s'='ABANDONS'
Can you help me to learn more?
(Other definitions for abandons that I've seen before include "Deserts, gives up completely" , "Deserts, leaves alone" , "Deserts, never intending to return" , "Deserts, say a sinking ship" , "Deserts, forsakes" .)
