Learn English Idioms – By The Book

MichaelADIdioms & Slang

What does the idiom BY THE BOOK mean?

Here is the meaning of by the book.

When you do something by the book, you follow the rules exactly. We usually use by the book to show that someone is not flexible about using the rules.

  • When it comes to the vacation policy, my boss always goes by the book.
  • The teacher is very strict and grades each term paper by the book.

Keep in mind the best way to remember this or any vocabulary in English is to take the word or phrase write it in a sentence that’s true for you or true in your world and then memorize your sentences.

You can even take your sentences and write them in the comments below. I would love to see your examples. And if you really want help with vocabulary, sign up for my free vocabulary workshop (see below).
