Thank you! I have some general knowlege of the history of BASIC English, but I was unaware of the letter by Churchill. Just looked briefly, will look thoroughly, but I’m interested because he went from no to yes. I saw mention of it’s effectiveness for wartime communication and spreading Anglo influence (both make sense to me: ok for first, worried for second). It might be more efficient, but I would have suspected Churchill to rather want to hang onto nuance. He’s known for concise quips, so maybe brevity nuance for him.
I will look more. Thank you!
