Definition of oral

The word "oral" has its roots in Latin. The Latin word "os" means "mouth" or "opening of the mouth." From this Latin root, the word "oral" was derived, meaning "relating to the mouth" or "spoken." In the 15th century, the term "oral" emerged in English, initially referring to something that is spoken or verbal, as opposed to written. Over time, the meaning of "oral" expanded to include other senses, such as relating to the mouth or lips, or being conducted through conversation or dialogue. Today, the word "oral" is used in various fields, including medicine (e.g., oral medicine), education (e.g., oral presentation), and linguistics (e.g., oral language). So, the next time you have an oral presentation or examination, remember the Latin roots of this word!
