The term "dropping for" implies a sudden decrease or decline, and its antonyms describe the opposite. "Increasing," "surging," and "rising" all suggest growth and development, indicating an upswing rather than a downturn. "Improving," "expanding," and "strengthening" can also convey a positive connotation, implying progress, betterment, or enhancement. Conversely, "declining," "falling," and "weakening" are direct antonyms for "dropping for," suggesting a negative trend. Words such as "shrinking," "contracting," and "diminishing" are also used to describe a decrease in size or extent. The choice of antonym will depend on the context in which it is used, but the contrast with "dropping for" is clear.
