What is ersatz meaning?

"Ersatz" is a German word that means "substitute" or "replacement". In English, it is often used to describe a cheaper or inferior substitute for something of higher quality or value, or anything that is meant to imitate or mimic something else. For example, an "ersatz coffee" is a coffee substitute made from grains, while an "ersatz leather" is a synthetic material meant to imitate real leather. The word can also be used in a negative way to suggest that something is fake or of poor quality.
