What is another word for mach?
Pronunciation: [mˈɑːk] (IPA) 
The word "mach" is usually used as a prefix to describe something that is fast or capable of high speeds. However, there are several synonyms that can be used in its place. For example, the word "velocity" is often used to describe the speed of an object, and "speedy" can be used as a replacement for "fast." Additionally, "swift," "quick," "rapid," and "fleet" are all synonyms that convey a sense of speed and acceleration. "Hasty" and "expeditious" can also be used to imply an urgency or quickness, though they may not necessarily connote speed. By using these synonyms, writers and speakers can add variety and nuance to their language while still conveying the idea of speed and acceleration.
