Root Explanation

Plasmoid is formed from "plasma" (from Greek "plasma", meaning something molded or formed) and the suffix "-oid" (meaning resembling or like). The word "plasmoid" refers to something that resembles or has the characteristics of plasma.

Memory Tip

Think of 'plasma' as something that is 'molded' or 'formed', and '-oid' means 'like' or 'resembling'. So, a plasmoid is something that resembles plasma.
