Root Explanation

Hemichordate → It is formed from "hemi-" (meaning half) and "chordata" (from Latin *chordatus*, meaning having a cord or string). The term refers to animals that possess a structure resembling a notochord, but only partially, hence 'half-corded'.

Memory Tip

Think of 'hemi-' meaning half and 'chordata' referring to a cord-like structure. This helps you remember that a hemichordate has a structure that is like a notochord, but only partially.
