Etymology
the term capsid is a modern scientific coinage, derived from the latin word 'capsa', which means a box, case, or container. this root is also the source of english words like capsule and case. the suffix '-id' is commonly used in biological and scientific contexts to form nouns. therefore, the word's literal construction as "a box-like thing" perfectly describes its function as the protective protein container for a virus's core genetic material.
