Does every word have a vowel in it?

No, not every word has a vowel in it. There are words in the English language that are made up entirely of consonants. These are called consonant digraphs, and they are often used to represent sounds that are difficult to represent with a single letter.

Here are some examples:

* Shh

* Brr

* Pfft

* Hmm

These words don't have vowels, but they still represent sounds that we can understand.
