English speakers use the word "like" for many reasons. One way that we use "like" is to show hesitation. You hesitate when:
- you are unsure of something
- you're afraid that your words will make other people upset
- you can't think of the right word to complete your thought
Here are some examples:
You have to fill out a lot of, like, forms and paperwork.
I know that you're upset, but, like, maybe you should calm down.
This is a habit that English speakers (especially young people) have in spoken English. We don't usually use "like" this way in writing.
