Did you know that every virus has a capsid around it?

Yeah, I heard it's like a protective shell for the virus.

Root Explanation

Capsid → The word 'capsid' is derived from the Latin 'capsa' (meaning box or container) and the suffix '-id' (used to form nouns indicating a relationship or condition). The term refers to the protein shell that encloses the genetic material of a virus, resembling a box that contains something.

Memory Tip

Think of a 'box' ('capsa') that holds something important inside — that's what a capsid does; it contains the genetic material of a virus.
