It's often used in scientific and medical terms related to the mouth, as the mouth is considered the "entrance" to the digestive system, similar to a coastline being the entrance to a landmass.
Here are some examples of words that use the root "ora":
* Oral: relating to the mouth
* Oral cavity: the space inside the mouth
* Oral hygiene: practices related to keeping the mouth clean
* Oral medication: medication taken by mouth
* Oral surgeon: a surgeon who specializes in procedures of the mouth
* Oration: a formal speech, often given at a ceremony, comparing the speaker to a person standing on a shore and addressing the audience
* Orifice: an opening, especially in the body, like a mouth or a hole in a pipe
While "ora" primarily relates to the mouth, its literal meaning of "shore" can also be seen in some contexts, such as the word "oratory," which means a place for prayer or a formal speech, as it connects to the idea of a public platform or a speaker standing on a shore.
