点滴 (diǎn dī) literally means 'drops'—'点' refers to tiny points or specks, and '滴' means a single drop of liquid. Together, they evoke the image of small, gradual amounts, often implying something minimal yet continuous or cumulative. In everyday usage, it commonly describes tiny quantities of time, effort, money, or progress—e.g., '点滴积累' (gradual accumulation). The word carries a positive, patient connotation, suggesting that even minute contributions matter over time.

In medical contexts, 点滴 is a widely used abbreviation for intravenous (IV) therapy—literally 'drip infusion', where fluids or medicine are delivered slowly drop by drop into a vein. This usage is so common in hospitals and clinics that many Chinese speakers use 点滴 alone to mean 'getting an IV'. It’s colloquial but universally understood in healthcare settings.
