What does the prefix tachy- mean?

Explanation:
Tachy- means rapid or fast. This Greek prefix is used in medical terms to indicate speed, which is why you see tachycardia (a fast heart rate) and tachypnea (rapid breathing). The sense of speed is the clue you apply to terms with this prefix. Other options describe different ideas—slow would be brady-, between would be inter- or a related form, and weak isn’t conveyed by tachy-. So the fast or rapid meaning is the correct interpretation.
