“Dwindle” is similar in meaning to the verbs “diminish,” “reduce,” “decrease,” and “shrink.” It’s commonly used to describe when the volume, size, or power of something has become smaller. Ex: The number of customers coming to the restaurant has been dwindling because of the pandemic. Ex: Subway usage has dwindled as most people have been staying at home.
