usage is also, however, a concern for the prescriptive tradition, for which "correctness" is a matter of arbitrating style

In the descriptive tradition of language analysis, by way of contrast, "correct" tends to mean functionally adequate for the purposes of the speaker or writer using it, and adequately idiomatic to be accepted by the listener or reader

This is not an attempt to arrest the evolution of the language, but to correct mistakes.

If you’d like to give this approach to executing projects a try, now isthe perfect time.Start by picking one project you want to move forward on. It couldbe one you identified in Chapter 5, when I asked you to make foldersfor each active project.

I like to keep the ‘verb’ + ‘noun’ structure when writing button labels — this makes the action more prescriptive, e.g. ‘Save post’, ‘Next step’, etc, as opposed to ‘Save’, ‘Next’

my point is that using "into" in such a case is just as incorrect as using "inas" would be. The fact that people make mistakes doesn't change this.

In a sentence like Log in as "admin", you'd never write "*inas" as one word. Same thing with "in" and "to" when they just happen to end up next to each other in a sentence.

That sounds like a pretty prescriptive attitude towards the language.
