Eli5 – How would you explain when to use “I’ll” vs “I will” to someone who isn’t a native speaker?

Question

For example why does it sound unnatural to say “I’ll not use this for profit.”?

Answer 1

Your example is brilliant,

To be honest, I don’t know that any sort of rule applies to “I’ll not use this for profit.” you just sort of have to know that its wrong.

“I’ll use this for profit” sounds absolutely fine

And so does “I will not use this for profit”.

I wouldn’t sweat it, *unless you’re a Russian Sleeper, and don’t want to be caught*.

Most people will know what you mean.
