Cough
Tos
What it means
Coughing is a reflex that keeps the throat and airways clear. Although it can be annoying, coughing helps the body heal or protect itself, but too much coughing may mean a disease or disorder. Some coughs are dry and others are productive; a productive cough is one that brings up mucus, which is also called phlegm or sputum. Coughs can be acute or chronic. In the MedlinePlus encyclopedia, acute coughs usually begin rapidly and are often due to a cold, flu, or sinus infection, subacute coughs last 3 to 8 weeks, and chronic coughs last longer than 8 weeks. Common causes include allergies, asthma, viral infections, and gastroesophageal reflux disease. MedlinePlus says to call 911 or the local emergency number for shortness of breath or difficulty breathing.
Cough in Spanish
- Spanish term
- Tos
- Gender and article
- feminine: la tos
- Pronunciation
- TOHS
Tos is the word used by MedlinePlus en español and the Real Academia Española dictionary, which marks it as a feminine noun (la tos) and defines it as a convulsive, noisy movement of the respiratory apparatus. The MedlinePlus en español encyclopedia prints the plural toses. The adjectives follow the feminine noun: tos seca (dry cough), tos productiva (productive cough), tos aguda, tos subaguda and tos crónica.
For what a productive cough brings up, MedlinePlus en español writes moco and says it is also called flema or esputo. The dictionary also records set expressions built on the word: tos perruna, a harsh cough with a characteristic noise produced by spasms of the larynx; tos convulsa or tos convulsiva, a cough that comes in violent, intermittent fits; and tos ferina, which it refers to the one-word entry tosferina. Other words on the Spanish pages are resfriado (cold), gripe (flu), pastillas para la tos (cough drops) and estridor, a high-pitched sound when breathing in.

Your right to an interpreter in the United States
If English is not your primary language and you have difficulty communicating in English, you may need an interpreter or a translated document when you visit a doctor or dentist, go to the emergency room or pick up a prescription. The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
You can ask when you make the appointment or at the front desk: "I need an interpreter, please." «Necesito un intérprete, por favor.»
