What is the meaning of the word "memento"?

The term "memento" refers specifically to an object kept as a reminder of a person, place, or event. This interpretation aligns perfectly with the definition of something that serves as a reminder. Often, mementos are souvenirs or keepsakes that hold sentimental value and evoke memories. For instance, someone might keep a ticket stub from a concert or a souvenir from a trip as a memento of their experience.

In contrast, the other options do not encapsulate the essence of the word. Cultural foods or drinks pertain to traditions and heritage, but they do not inherently serve as reminders of past experiences. A formal event or celebration relates to social gatherings rather than personal reminders. Lastly, a political document or treaty encompasses legal or formal agreements, which are not personal keepsakes or reminders in nature. Thus, the selected answer accurately captures the meaning of "memento" in a direct and relevant manner.
