How do you use circumflex in a sentence?

You can't use the word "circumflex" directly in a sentence to mean the accent mark. You need to use it to describe the mark itself. Here are a few examples:

* "The word "hôtel" has a circumflex over the "o".

* "The circumflex is a diacritical mark used in various languages."

* "French uses the circumflex to indicate a lost 's' in some words."
