be soft on

'treat leniently' is the definition.
(I know this)

'those initiating some offensive frivolity in british school' is the wordplay.
I cannot quite understand how this works, but
'those' could be 'yon' (historic English pronoun equivalent to 'those') and 'yon' is located in the answer.
'some' could be 'a' and 'a' is found within the answer.
'school' could be 's' and 's' is located in the answer.
The remaining letters 'goe' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?

(Another definition for go easy on that I've seen is " To spare harsh treatment".)

I've seen this clue in The Telegraph.
