I just read about something called gliosis in my biology book.

Oh, what’s that about?

Root Explanation

**Gliosis** → It is formed from "glia" (from Greek *glia*, meaning glue) and the suffix "-osis" (meaning a condition or process). The term "gliosis" refers to a condition involving the proliferation of glial cells in the nervous system, often in response to injury or disease.

Memory Tip

Think of 'glia' as 'glue' in the brain, and remember that 'gliosis' describes a condition where this 'glue' increases in response to damage.
