Coordination can start to go around motorway (6)
I believe the answer is:
timing
'coordination' is the definition.
(thesaurus)
'can start to go around motorway' is the wordplay.
'can' becomes 'tin' ('tin' can be a synonym of 'can').
'start to' suggests taking the first letters.
'around' indicates putting letters inside.
'motorway' becomes 'mi' (resembles M1, English motorway).
The first letter of 'go' is 'g'.
'tin'+'g'='ting'
'ting' going around 'mi' is 'TIMING'.
(Other definitions for timing that I've seen before include "Comedic skill" , "Entrails used as food" , "Regulating" , "Judgement of when something should be done" , "Choice of moment" .)
