Go astray and start to sabotage commissioned journeys (7)
I believe the answer is:
errands
'commissioned journeys' is the definition.
'errands' can be an answer for 'journeys' (errand is a kind of journey). I'm unsure of the 'commissioned' bit.
'go astray and start to sabotage' is the wordplay.
'go astray' becomes 'err' (to err is to make an error or go the wrong way).
'start to' suggests taking the first letters.
The initial letter of 'sabotage' is 's'.
'err'+'and'+'s'='ERRANDS'
Can you help me to learn more?
(Other definitions for errands that I've seen before include "Delivery journeys" , "trips on someone's behalf" , "Short journeys" , "charges" , "Task-oriented trips" .)
