Root Explanation

Metamer is derived from the Greek "meta-" (meaning beyond or change) and "meros" (meaning part). The term refers to a part that changes or is beyond the usual classification, often used in the context of biology to describe segments of organisms that are similar but not identical.

Memory Tip

Think of 'meta-' meaning 'beyond' and 'meros' meaning 'part' — this helps you remember that a metamer refers to a part that goes beyond the usual classification.
