Good morning, I was wondering why do we say "toothbrush" and not "teethbrush". A toothbrush brushes the teeth and not a tooth.

Good morning,
Thanks for using our services !
First off, the plural form of toothbrush is toothbrushes as this is an irregular plural noun finishing in -ch. In that situation, we must add the -es ending to the singular form of the word to make it plural.
You might have gotten confused with the word tooth which becomes teeth when plural. This word is also an example of an irregular plural as this is an exception.
In fact, there are hundreds of irregular plurals in the English language and the best way to learn them is to memorize them by getting used to hearing them in their singular or plural form as well as read them in books and on different platforms.
