People are always taking risks and as a result they are always likely to have accidents. Let’s learn how to warn someone in English.

We warn people about the dangers in many different ways.

These are often referred to as warning signs when it is official.

As an example a local government will put up (erect) warning signs like Danger keep out. This is to stop people going into a restricted area.

A farmer might put up a notice on his field Beware of Bull, Keep out.

And house owners often put up notices on their gates (particularly for the postman!) Beware of the Dog.

This warns people in advance so if anything happens the owners of the land (government or the farmer) have some protection against a legal action.

How to Warn Someone in English?

There are many more informal ways of warning people in English. Here are some of them:

1. MIND YOUR HEAD

Where a ceiling or door is low and you might possibly bang (hit) your head then these warning signs or posters are put up to help you.

2. MIND OUT OF THE WAY or KEEP OUT OF THE WAY!

This is often shouted when we are in danger of bumping into somebody who is too close to us.

For example, you are running along the street as you are late for the bus or tram. You shout at the people (politely) to mind out of the way or keep out of the way so you can get by more quickly.

3. TAKE CARE (OF YOURSELF)

be careful, be cautious, keep yourself safe

Take care driving in foggy conditions.

We can also use this phrase when we’re saying goodbye to family or friends.

4. BE CAREFUL

pay attention to what you are doing, be cautious

Be careful when using this new app and paying by card! 

5. IF I WERE YOU

We’re using this expression when we want to give someone a piece of advice.

If I were you, I wouldn’t drive home tonight.

Many of warnings in English are written in the form of phrasal verbs (verb + preposition) but always remember if you want it to sound important or serious then when writing it use the exclamation mark! Or when speaking you must raise your voice (not necessarily scream or shout) to indicate it is a warning.

  • Look out!
  • Watch out!
  • Watch it!
  • Careful!
  • Keep out!

All of these warnings in English basically mean the same.

  • Look out my hands are full I might drop the plates!
  • Watch out I am right behind you do not move!
  • Watch it you nearly knocked into me!
  • Careful you are spilling the wine!

If you are in a room (your bedroom) trying to get some peace and quiet then if someone knocks on your door you might say “go away, I am busy”.  Teenagers will often use these phrases to warn their parents not to disturb them:

GO AWAY CAN’T YOU SEE I AM BUSY 

or

GET OUT I AM BUSY!

(NEVER use it with people you don’t know as this is very impolite)

As in many languages, warnings in English can be given in many ways to advise us of a possible danger or risk so it is always a good idea to heed (take notice of) that warning.
