A word about colds, not bathrooms

Constipado

kon-stee-PAH-doh — Having a cold — NOT "constipated"

"Estoy constipado, no puedo dejar de estornudar."
I have a cold, I can't stop sneezing.

"Constipated" in the bathroom sense is "estreñido." Saying "estoy constipado" to a Spanish doctor just means you have a stuffy nose.

"Every winter, someone tells their Spanish host family the wrong thing by mistake and gets a very confused reaction."— Graciela
