Nas-: The Combining Form for “Nose” – A Deep Dive into Meaning, Usage, and Examples
When you encounter unfamiliar medical or scientific terms, a useful trick is to break them down into smaller parts. One such combining form is nas-, which is derived from the Latin word nasus, meaning nose. So in this article, we will explore the definition of nas-, its origins, how it appears in everyday language, and a comprehensive list of terms that use this root.

By the end, you’ll be able to recognize and decode any word that includes nas- with confidence.
Introduction
The human nose is a fascinating organ, serving functions from breathing and smelling to shaping our facial profile. On the flip side, in medical terminology, the nose is frequently referenced when describing conditions, procedures, or anatomical structures. The combining form nas- is the linguistic bridge that allows clinicians, scientists, and students to construct precise, universally understood terms. Understanding nas- not only enhances your vocabulary but also deepens your appreciation for how language evolves to meet the needs of science and medicine.
The Root: Latin nasus
- Origin: Latin
- Meaning: nasus = nose
- Pronunciation: nah-sus
The Latin root nasus is straightforward: it directly refers to the anatomical nose. That said, over centuries, as Latin remained the lingua franca of scholars, this root was adopted into Greek, Old French, and eventually modern English. When Latin roots are used in medical terminology, they often appear as nas- or nasal depending on the grammatical context.
What Is a Combining Form?
A combining form is a root that can attach to other roots, prefixes, or suffixes to create a new word. Unlike a standalone root, a combining form usually ends with a vowel (most commonly a or i) that facilitates smooth pronunciation when attached to the next element. Nas- is a classic example:
The official docs gloss over this. That's a mistake.
- nas + al → nasal
- nas + o + tomy → nasotomy
- nas + o + scopy → nasoscopy
