Definition
Ameboid describes something that resembles an amoeba, a single-celled organism known for its irregular shape and ability to move by extending pseudopods ('false feet'). It implies a fluid, changeable form without a fixed structure. Think of it as the opposite of a rigid, geometric shape. It's not just about being shapeless, but about actively changing shape to move or engulf food. Thus, 'ameboid' suggests adaptability and dynamic form.
