Directly:
* Apert: (archaic) meaning "open," "uncovered," or "exposed." This word is rarely used in modern English.
Indirectly:
* Aperture: A natural or artificial opening.
* Aperitive: A drink that stimulates the appetite.
* Apertometer: A device for measuring the aperture of a lens.
It's important to note that the root "apert" is often combined with other prefixes and suffixes to form new words, such as "de" in "de-aperture" or "re" in "re-aperture."
While "apert" itself isn't used frequently, it contributes to the formation of words that relate to opening, exposure, and uncovering.
