Which word defines a strong desire for something that belongs to someone else?

The choice "Covet" is correct because it specifically denotes an intense, often unbidden desire for something that someone else possesses. This term is rooted in a sense of longing and yearning, particularly for material possessions, status, or qualities that are envied in others. Coveting implies not just wanting something, but having an envious craving for it, highlighting the emotional and ethical complexities that can arise from such a desire.

The other options do not align with this definition. Tolerate suggests the ability to endure or accept something unpleasant without inclination towards desire. Reject indicates a refusal or dismissal, which is contrary to the idea of wanting something. Encourage involves promoting or supporting someone or something, which is unrelated to the idea of desiring another's belongings. Thus, "Covet" stands out as the term that accurately captures the essence of longing specifically for what belongs to someone else.
