The word Yearn means to have an intense feeling of longing for something, typically something that one has lost or been separated from. It expresses a strong, often wistful, desire or craving. Therefore, the most fitting synonym among the options is Desire (option B).
When someone yearns for something, they feel a deep and often persistent wish or longing. For example, one might “yearn for home” after a long journey, or “yearn for success” in their career. The feeling is typically more profound and emotional than a simple wish. Option A, “Ignore,” means to disregard or pay no attention to, which is the opposite of yearning. Option C, “Reject,” means to dismiss or refuse, also contrary to the meaning. Option D, “Stop,” implies ceasing an action or state, which is unrelated. Understanding “yearn” helps to convey a powerful emotional longing, emphasizing the depth of a person's wishes or aspirations.
