Police Vocabulary

Police vocabulary is definitely not the first thing every English learner will pay attention to at the beginning of their language learning journey. However, those A-students who hanker after new words to achieve English proficiency will take time to memorize terms and slang from the police terminology list, especially if they are keen on detective films and tv shows. Plus, knowing some police vocabulary can save your life or help to report a crime at the end of the day. So, we strongly advise you to get deeper into the law enforcement vocabulary for your own good.

Police Vocabulary: Slang, Jargon, And Acronyms

It might seem surreal, but police officers do use official codes and acronyms as well as unofficial slang and jargon for better internal communication. Film writers didn't think all of those police phrases up just for fun. Instead, they serve to pass information clearer and mistake-free. Most of the police vocabulary is difficult to follow because, except for the police, nobody uses it. However, knowing police terminology can help you orientate in critical situations and understand movies about cops much better. Let's learn some police slang, jargon, and acronyms that officers tap into to remain their conversations discreet. 

Walkie talkie

This is a snag term for a portable radio police use to send and receive information. It was named like so because of the journalist reporting on the new invention during the war. 

Berries and Cherries

That is how police call the blue and red lights on patrol cars. Because of the light's colors and rounded shape, it reminds them of those fruits

Hookem and Bookem

This one decodes as handcuffing and booking someone into the system. Simply put, that's a police term for getting someone from the streets and putting them behind bars. 


To communicate effectively but briefly, police officers use a unique digital code for passing information through their radio. The most well-known among civilians is the ten-codes system. Basically, the ten plus another number has a particular meaning. For instance, 10-4 stands for «ok» or «message received.»

Taking a code 7

Some police codes don't refer to crimes, emergencies, or direct work situations. Cops also have codes to let others know about their personal needs, such as going to the bathroom or taking a lunch break. For example, taking code 7 refers to the last one. 


This is how police officers call a drunk driver to keep it short. It comes from California, where the government added to Vehicle Code section 23102 about the drunk driving violation, known as a "deuce.»

A house mouse

Police officers are brave and can cope with danger better than others. However, it doesn't mean everyone loves to go to the streets to deal with criminals daily. Some of them stay at the police station and work with papers. For such colleagues, cops coined the term "house mouse." It means the police officer who doesn't go out on patrol.


This police acronym decodes as "Forget It, Drive On.» Cops use it when they decide something is not worth their attention or assistance, and there is no need to stop the car. 

To Mirandize

This verb comes from the term Miranda Rights, which stands for the Constitutional rights that a person has while being under arrest. The officer must read an arrestee their right to Mirandize them. 

A Sam Browne

That's another way of naming an officer's belt. Cops call it that in honor of its inventor General Sam Browne. After losing his left arm, which made it difficult for him to draw his sword, the man came up with the idea of wearing a second belt over his right shoulder. 

The bus

If cops call for the bus, they mean an ambulance. The slang term comes from New York City. Decades ago, the first batch of ambulances was bought from the same vendor that sold NYC their school buses. So, police officers started to refer to them as buses. If a cop wants to emphasize that they need an ambulance fast, they will say, "put a rush on the bus."


It decodes as a Personally Owned Vehicle, the opposite of a patrol car. 

Ghetto bird 

That is an idiom that means a police helicopter. It got its name because of the 1993 song "Ghetto Bird" by Ice Cube. In lyrics, the artist refers to a helicopter as a bird that flies over the ghetto in search of a crime.


The term comes from rap music and means a stolen vehicle.

Knowing police vocabulary will benefit your English in everyday life, even if you have nothing to do with police in terms of work:

  1. You will finally dare to watch criminal and detective tv shows in English without subtitles. We know that watching English content where the characters constantly tap into specialized terms might be intimidating and unmotivating. But once you memorize police terms and definitions the movies and series about cops or the FBI will feel like fun again.
  2. Police terminology will help you fully participate in hot-topic discussions. Media always keep people informed about the crimes committed and significant trials like the one with Amber Heard and Johnny Depp.
  3. Most importantly, you will be able to get the gist of the criminal situation near you and act in the best way possible and blow the whistle to catch someone red-handed. 


What are slang words for police?

Calling a police officer simply officer, policeman, or policewoman is pretty formal. And having face-to-face communication with a defender of the law is the only correct way of addressing them. Nonetheless, in movies and day-to-day life, you will rarely hear someone referring to a police representative in such a way. Most likely, people will use some slang synonyms. In the UK, slang words for police are plod, peeler, and fuzz. The US police are called cop, bobby, copper, bogey, the boys in blue, bear, barney, and bull. There are some other slang words for law enforcement personnel. Detectives are dicks, FBI agents are federals, the feds or G-men. 

What is the police alphabet code?

The phonetic police code is a system of words and names that directly correlates to letters. As an English learner with some experience, you know that spelling and pronunciation in English differ a lot. That is why the US police developed a phonetic alphabet to clarify communication with dispatchers through radio, even if the radio traffic is fuzzy. It may take a little mortise to pass the information, but it also eliminates the need to repeat messages because the dispatcher received it correctly from the first attempt. The alphabet published by the International Civil Aviation Organization, or ICAO, in 1956 has been used in the United States and the United Kingdom.

The police alphabet consists of the following:

  1. A is Adam 
  2. B is Boy
  3. C is Charlie
  4. D is David
  5. E is Edward
  6. F is Frank
  7. G is George
  8. H is Henry
  9. I is Ida
  10. J is John
  11. K is King
  12. L is Lincoln
  13. M is Mary
  14. N is Nora
  15. O is Ocean
  16. P is Paul
  17. Q is Queen
  18. R is Robert
  19. S is Sam
  20. T is Tom
  21. U is Union
  22. V is Victor
  23. W is William
  24. X is X-Ray
  25. Y is Young
  26. Z is Zebra

What is a digit police code?

A digit police code is a numerical code for transmitting information through the police radio systems used by law enforcement personnel. Such codes correspond to specific situations, crimes, and states on duty. Police officers usually pronounce every code digit-by-digit to make their message clear to the receiver. Signals, incident codes, response codes, or other status codes vary by state, county, and agency. So, police officers always have to refresh their knowledge when changing their place of work. In general, it is more tactically advantageous and safe to use police code than explain what is going on with "plain language" so anyone could understand the police and act at a disadvantage. Nonetheless, all codes can be found publicly available on the Internet. That's how we know that, for instance, 10-54 corresponds to a hit-and-run accident, and 11-99 means that an officer needs help. 

What do police say in arrests?

If you are a fan of American movies and tv shows about police, detectives, and the FBI, you must have heard what the law enforcement personnel says to a suspect during the arrest. Usually, the US law representative informs a person why they are being arrested and reads their Miranda Rights. 

The Miranda Warning says: "You have the right to remain silent. Anything you say can and will be used against you in a court of law. You have the right to an attorney. If you cannot afford an attorney, one will be provided for you. Do you understand the rights I have just read to you?"

If the police officer forgets to read the Miranda Rights, the suspect will be released from the guard because the arrest was improper.
