Common nouns

If there is more than one thing, then it is a common noun. Don’t capitalize common nouns unless they are at the beginning of a sentence, or if the sentence implements title case capitalization. For example, there are multiple websites, so website is a common noun. But, WordPress is a unique website out of all of them, therefore, it is a proper noun.

Common nouns include most product categories, devices, features, and technology concepts such as email, laptop, machine learning, website, and server.
