All words have consonants in them, except for words that are made up of only vowels.
Here's why:
* Consonants are sounds made by partially or fully blocking airflow in your mouth.
* Vowels are sounds made with your mouth open, allowing air to flow freely.
For example:
* "Cat" has the consonants "c" and "t".
* "Apple" has the consonants "p" and "l".
* "A" is a word that only has a vowel.
