Way somebody emptied trunk (6)

Ross

I believe the answer is:

system

I'm a little stuck... Click here to teach me more about this clue!

'way' is the definition.
(I've seen this before)

'somebody emptied trunk' is the wordplay.
'emptied' suggests removing the centre.
'trunk' becomes 'stem' (I can't justify this - if you can you should give a lot more credence to this answer).
'somebody' with its centre taken out is 'sy'.
'sy'+'stem'='SYSTEM'

Can you help me to learn more?

(Other definitions for system that I've seen before include "Organised structure for arranging or classifying" , "Organised scheme" , "Plan of action" , "Organized scheme" , "Arrangement of things working together" .)
