Noun
/se'izmo/
Usage: "Zeísmo" is a term used in the field of medicine, specifically in otorhinolaryngology. It refers to the condition where a person substitutes the /θ/ phoneme (the 'th' sound in English words like "think") with a /s/ sound, particularly in Spain. This term is more commonly used in written medical contexts rather than in everyday oral speech.
"Zeísmo" is not commonly used in idiomatic expressions in Spanish.
The term "zeísmo" comes from the Greek word "zyo," which means "to live" or "to breathe." In this case, it refers to the characteristic sound produced when the /θ/ phoneme is replaced with a /s/ sound in speech.
