What is the meaning of the medical combining form hydr/o?

Explanation:
Hydr/o means water. The form comes from the Greek word hydor for water, and it’s used in medical terms to show that water is involved—whether referring to the substance itself or to the body’s water balance. That’s why words about water balance (hydration, dehydration) or water in a body part (such as hydrocephalus or hydrocele) use this root. Air would come from aer/o or pneum/o, and blood from hemat/o or sanguin/o, so hydr/o specifically points to water. While “fluid” is a general idea of a watery substance, hydr/o identifies water in particular.
