Root Explanation

Actinia is derived from the Greek word "aktis" (meaning ray or beam) combined with the suffix "-ia" (used to form nouns). The term refers to a group of marine animals known as sea anemones, which have a radiating structure resembling rays.

Memory Tip

Imagine the 'rays' ('aktis') of a sun shining outwards, just like the tentacles of a sea anemone, which is what 'actinia' refers to.
