The word "makes a purchase" refers to the act of buying something. It is a common activity in our daily lives. However, sometimes you need to express the opposite meaning of "makes a purchase." In this case, you may use words like "returns," "exchanges," "gives away," "sells," "donates," and "loses." These antonyms convey different situations where someone might not be making a purchase, but instead returning or exchanging something previously bought, giving it away, selling it to someone else, donating it to charity, or losing it accidentally. Using antonyms effectively can help you communicate your message clearly and convey a different meaning than the usual one.
