What is the only word in English language that when capitalized changed from a noun or verb to nationality?

This is a bit of a trick question! There isn't a single word in the English language that changes from a noun or verb to a nationality solely by being capitalized.

Here's why:

* Capitalization for Nationality: Capitalization is used to denote proper nouns, which include names of people, places, and nationalities. So, "English" is capitalized because it refers to the nationality and language of people from England.

* Nouns and Verbs: Nouns and verbs can be used to describe nationality, but the capitalization doesn't change their meaning. For example:

* "The English language is spoken in many countries." (English is a noun here, referring to the language)

* "She is English." (English is an adjective here, describing nationality)
