Practise on last means of transport (8)
I believe the answer is:
rehearse
'practise' is the definition.
('rehearse' can be a synonym of 'practise')
'last means of transport' is the wordplay.
'last means of' becomes 're' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'transport' becomes 'hearse' (hearse is a kind of transport).
're'+'hearse'='REHEARSE'
'on' is the link.
Can you help me to learn more?
(Other definitions for rehearse that I've seen before include "What actor does to prepare for play" , "Practise (one's lines)" , "prepare for performance" , "Practise like actor" , "Practise parts" .)
