One-word substitution (dietary habit): Choose the correct adjective for a person or animal that eats all kinds of food, both plant and animal matter. Context: Contrast with terms that mean ‘‘all-knowing’’ or unrelated qualities. Instruction: Select the best option from the list.

Given data

• Target meaning: one who eats everything.
• Options: Omnivorous, Omniscient, Irresistible, Insolvent.

Concept / Approach
Omnivorous comes from Latin omni- (all) + vorare (to eat) → eats plants and animals. Omniscient = all-knowing; irresistible = impossible to resist; insolvent = unable to pay debts.

Omnivorous
