In English, we normally use just 1 negative word per sentence.  In other languages, such as Spanish or Portuguese, it is normal to use 2 negatives.  Yet in English this is called a ‘double negative’, which is not allowed.

For example, the English sentence “I don’t have nothing” is not correct because there are 2 negatives (don’t & nothing).

By using two negatives, it actually changes the meaning to a positive.  

“I don’t have nothing” literally means “I have something’.

So to correct this sentence, we have two options.  

We could write:

‘I don’t have anything’ OR ‘I have nothing’.

So let’s be positive, not (double) negative!
