- Everyone's inner language police have an evil and good side.

The good language police guide and help other people to use a language that follows the norm that we agree should apply right now.

But when it turns to the bad side, you can see people standing and shouting at other people that they are not allowed to say "actually".

Sara Lövestam draws the history of the language police, from the Middle Ages onwards.

A milestone occurred in 1900 when the expression "it's actually called ..." first appeared in the Swedish public.

Sara Lövestam also reviews linguistic crimes.

Improper use of "they" and "them" belongs to the heavier category.

Myself quite kind

- They and they are pronouns that are used often and if they are used incorrectly, it can contaminate an entire text.

Other words and expressions are used less frequently and only destroy in the places where they occur. 

Sara Lövestam considers herself a rather kind language policeman. 

- I correct those I love.

I want both children and adults in my vicinity to know that it is called "pull everyone over a ridge" and not "pull everyone over an edge" so that they will not be judged by other people.

But I'm not someone who beats linguistic rules in anyone's head.
