Order collapsed -- that hurt transport (10)
I believe the answer is:
fellowship
'order' is the definition.
(synonyms)
'collapsed that hurt transport' is the wordplay.
'collapsed' becomes 'fell' (I've seen this in another clue).
'that hurt' becomes 'ow' (exclamation of pain).
'transport' becomes 'ship' (synonyms).
'fell'+'ow'+'ship'='FELLOWSHIP'
(Other definitions for fellowship that I've seen before include "Association" , "Academic honour" , "club" , "Friendliness; guild" , "camaraderie" .)
