However, depending on the context, there might be different nuances to how you might say it in English:
* As a dance: "Bolero" is used as the name of the dance.
* As a musical piece: "Bolero" can also refer to a musical composition, like the famous "Bolero" by Ravel.
* As a garment: "Bolero" refers to a short, fitted jacket.
So, "bolero" is already the English word, but its meaning can change based on the situation.
