noise

I'm a little stuck... Click here to teach me more about this clue!

'row' is the definition.
(row can mean a disturbance or noise)

'no one's bottom shown in savile' is the wordplay.
'bottom' indicates one should take the final letters.
'shown in' means one lot of letters goes inside another.
'savile' becomes 'ie' (I can't explain this - if you can you should give a lot more credence to this answer).
The final letter of 'ones' is 's'.
's' going inside 'ie' is 'ise'.
'no'+'ise'='NOISE'

Can you help me to learn more?
