Questions & Answers about Mam kaszel i katar, ale nie mam gorączki.
Polish normally uses mieć (mam = I have) with many illnesses and symptoms, just like English “have”:
- Mam kaszel. – I have a cough.
- Mam katar. – I have a runny nose / I have a cold (mild, stuffy/runny-nose type).
- Mam gorączkę. – I have a fever.
You do not say jestem kaszlem or jestem katarem (I am a cough / I am a runny nose), just as in English that sounds wrong.
However, for general states you can also use adjectives with być (to be):
- Jestem chory. – I am ill/sick.
- Jestem przeziębiony. – I have a (mild) cold / I am chilled/snippling.
So:
- For specific symptoms or illnesses: usually mam
- noun.
- For overall condition: jestem
- adjective (chory, przeziębiony, osłabiony, etc.).
