Started prohibition, say, inside (5)

Ross

I believe the answer is:

began

'started' is the definition.
('begin' can be a synonym of 'start')

'prohibition say inside' is the wordplay.
'prohibition' becomes 'ban' (synonyms).
'say' becomes 'eg' (both can mean 'for example').
'inside' indicates putting letters inside.
'ban' going around 'eg' is 'BEGAN'.

(Another definition for began that I've seen is " Commenced, started".)

I've seen this clue in The Mirror.
