Speak not injurious words neither in jest nor earnest; scoff at none although they give occasion.

Don’t use language instrumentally

Pay no attention to harsh words uttered by others.

Never use a metaphor, simile, or other figure of speech which you are used to seeing in print. Never use a long word where a short one will do. If it is possible to cut a word out, always cut it out. Never use the passive voice where you can use the active. Never use a foreign phrase, a scientific word, or a jargon word if you can think of an everyday English equivalent. Break any of these rules sooner than say anything outright barbarous.

I am pleased to announce that I've decided to go net-zero on swear words and bad language. In the event that I should say something inappropriate I pledge to compensate that by saying something nice. #COP26,

I have noticed that nothing I have never said ever did me any harm.

There is no such thing as a dirty word. Nor is there a word so powerful, that it's going to send the listener to the lake of fire upon hearing it.

We should never say anything with an air of authority, nor show any superiority of mind. We should avoid far-fetched expressions, expressions hard or forced, and never let the words be grander than the matter.

Don't, Sir, accustom yourself to use big words for little matters.

I have never been hurt by what I have not said.

Don't ever say this to me, "Are you O.K.?" It's like "Yeah, motherfucker, I'm fine."

"I'd never yell, "Good luck!" at anybody. It sounds terrible, when you think about it."

No panegyric needs their praise record;
An Englishman ne'er wants his own good word.

Sir, with no intention to take offence, I deny your right to put words into my mouth.
