What does the prefix tachy- mean, and provide an example term?

Explanation:
The prefix tachy- means fast or rapid. In medical terms, tachycardia literally means a fast heart rate, since cardia refers to the heart. This makes tachycardia a clear, concrete example of tachy- showing how the prefix signals speed in a specific body part. You can see the same idea in tachypnea, which uses tachy- to mean rapid breathing, illustrating how the same prefix working with different roots describes speed in various systems. The prefix does not mean slow or sharp, which is why brady- refers to slow and tachyphagia would describe rapid eating, not a sharp quality. So the best match for what tachy- means is fast, with tachycardia as a precise example.
