Note from 13 January 2023

For language changes inside a paragraph, MDN suggests we can use the i element:
https://developer.mozilla.org/en-US/docs/Web/HTML/Element/i

That's what I thought was one of the new use cases for i.

A @[email protected] page about “Declaring language in HTML” (so @[email protected] ?) says we should use a span, div or bdi:
https://www.w3.org/International/questions/qa-html-language-declarations.en#usingspan

So no i after all?
