Fake Grammar

In the 1800s, academics believed Latin was perfect and English needed to be more like Latin, and so some Latin grammar rules were imposed on English. From a linguistic and practical point of view, this was ridiculous. Here are two of those fake rules that must be ignored for English to fully be itself.

You can’t put a preposition at the end of a sentence 

Why not? Because it’s impossible in Latin and other Romance languages. In English, it’s a piece of cake.

I want to know which box it’s in.
Where are you from?
Pick the one above.

Just imagine the awkwardness created in trying to avoid ending the sentences with prepositions:
I want to know in which box it is.
From where are you?
Pick the one that is above the others.

You can’t split infinitives

Again, this is impossible to do in Romance languages but easy in English.

I want you to always remember me.
I told you to not do that.
You need to badly see a doctor.
(The infinitives are to remember, to do, to see.)

Languages come with their own laws that native speakers naturally acquire. Stop trying to override nature and shackle our language, 19th-century snobs.
