The word for “suit” in Spanish is “traje”. This term is commonly used to refer to a man’s suit, which typically includes a jacket and trousers. For example, you might say, “Él lleva un traje elegante” to mean “He is wearing an elegant suit.”
In some contexts, especially in Latin America, the word “terno” is also used to refer to a suit. However, “traje” is more widely understood across Spanish-speaking countries.
It’s important to note that the word “traje” can also refer to other types of outfits or costumes, depending on the context. For instance, a traditional costume might be called a “traje típico.”
