What is the word for the "runny" excretion from someone's nose called? from this link

Runny nose
is the idiom that Americans use to describe what happens when your nose runs (that is, when liquid comes out of your nose because of a cold, allergy, or crying). This is the term for the general condition of having a running nose and is used in a sentence like the word cold when it refers to an illness.

What is this “liquid that comes out of your nose” called in English?

  • To clarify, you would like a single word for "a person who has a runny nose"? – Mari-Lou A Mar 7 '17 at 12:00
  • Or do you want an alternative expression for "runny nose"? OR Would you like to know the name of the "runny" excretion which appears when people have bad colds? – Mari-Lou A Mar 7 '17 at 12:02

    I only posted an answer because providing answers in comments is not always productive, and you had two answers in comments with no follow up. For me, phlegm is usually thick, sometimes coloured and something you normally cough up if you have a very bad cold. – Mari-Lou A Mar 7 '17 at 12:57

Depending on your preference:

snot (informal), nasal mucus (formal) or nasal discharge (medical-sounding)

The correct medical term for runny nose is

Rhinorrhea or rhinorrhoea is a condition where the nasal cavity is filled with a significant amount of mucus fluid. The condition, commonly known as a runny nose, occurs relatively frequently. Rhinorrhea is a common symptom of allergies (hay fever) or certain diseases, such as the common cold. It can be a side effect of crying, exposure to cold temperatures, cocaine abuse or withdrawal, such as from opioids like methadone. Treatment for rhinorrhea is not usually necessary, but there are a number of medical treatments and preventive techniques available.


From WebMD.com

Mucus is something everyone has, and some people wish they had a lot less of the stringy, gooey stuff. Sure, it can be gross to blow globs of snot into tissue after tissue when you have a cold or sinus infection, but mucus actually serves a very important purpose. […] during an allergic response to an offending trigger, such as pollen or ragweed, most cells in your body squeeze out a substance called histamine, which triggers sneezing, itching, and nasal stuffiness. The tissue of the mucus membranes starts leaking fluid, and your nose begins to run.

    Not so much "correct" as "technical." – user210771 Mar 7 '17 at 19:14
  • There they are a-doin' it, just sittin' there a-chewin' it, thinkin' it's gum but it'snot. – mbomb007 Mar 7 '17 at 22:33
  • Wow! The next time I have a cold I'm going to tell people I have rhinorrhoea to see what their reaction is! – CJ Dennis Mar 7 '17 at 22:38

    @CJDennis: Reminds me of a lady I knew in high school who found it the height of hilarity to go to a fancy restaurant and (in a stage whisper) say something like: "Oh my god! There's a man masticating in public." – Jerry Coffin Mar 8 '17 at 0:50

When the liquid is thin, and non-viscous it can be called rheum.

A watery fluid that collects in or drips from the nose or eyes.

Technically speaking, the thin fluid coming from your nose due to cold weather (and not due to illness) is mostly water, which is condensed from the water-vapor rich air coming from your lungs.

    so what do you call it ? – Moudiz Mar 8 '17 at 8:26

    "mostly water" covers a large proportion of the liquids we encounter, making it pretty unhelpful as a description. Soup is mostly water, and so is eyewash, but you really don't want to get them confused. – AakashM Mar 8 '17 at 8:57

    Though interesting, this doesn't actually answer the question asked. The question is about the stuff that runs out of your nose when you have a cold, not when you are cold. – AndyT Mar 8 '17 at 11:44
  • @AakashM "mostly water" in comparison to other fluids coming from the nose. – Zoltan K. Mar 10 '17 at 8:17

    The human body as a whole is mostly water. Water other fluids commonly come from the nose when you have a runny nose? – Barmar Mar 13 '17 at 22:52
