Not all come on silent journey to work (7)
I believe the answer is:
commute
'journey to work' is the definition.
I can't judge whether this defines the answer.
'not all come on silent' is the wordplay.
'not all' means to remove the last letter (not all of the word).
'on' is a charade indicator (letters next to each other).
'silent' becomes 'mute' (synonyms).
'come' with its last letter taken off is 'com'.
'com'+'mute'='COMMUTE'
Can you help me to learn more?
(Other definitions for commute that I've seen before include "Travel regularly to work" , "make AC/DC split the > daily journey" , "Travel daily to work; mitigate" , "Exchange - travel to work" , "To reduce severity of the punishment" .)
