The word improvisates does not have an established etymology as it is not commonly used in the English language. It appears to be a derived form of the verb improvise, referring to the act of spontaneously creating or performing something without prior preparation. The term improvise comes from the Latin word improvisus, which means unforeseen or unforeseeable. From there, improvisus evolved into the Italian word improvvisare, which means to perform extemporaneously. Eventually, improvise entered the English language around the late 18th century. However, improvisates is not a standard form or conjugation of the verb improvise.
