Use of Double Negation

Use of Double Negation :

It is improper to use double negation, unless one consciously uses it to create effect.

For example :

'He didn't tell him not to do it' makes it ambiguous, resulting in issues in decoding the meaning; one can more easily say 'He didn't stop/prevent him from doing it'.

'I would never not listen to you' could simply be replaced with 'I would always listen to you'.

'I am not speaking to nobody today' should be replaced with 'I am not speaking to anybody today'.

'There is never nothing on the table' should be replaced with 'There is always somethingon the table'.
