Root Explanation

**Nauplius** → The word 'nauplius' comes from the Greek 'ναυπλιος' (nauplios), which is derived from 'ναῦς' (naus, meaning ship) and 'πλοῦς' (plous, meaning sailing or voyage). The term refers to a mythical figure associated with shipbuilding and navigation, thus connecting it to the concept of ships and sailing.

Memory Tip

Imagine a ship ('ναῦς') setting sail on a voyage ('πλοῦς') — this helps you remember that 'nauplius' relates to ships and navigation.
