膨胀

• 拼音: péng zhàng
• 汉字拆解: 膨 = 月 + 彭 (flesh + full resounding — body swelling outward); 胀 = 月 + 长 (flesh + grow — body growing in size)

含义

To expand; to swell; to inflate. Describes physical expansion caused by heat or pressure, or the unchecked metaphorical growth of ambitions, costs, or populations.

Used both literally (thermal expansion, swelling) and figuratively (欲望膨胀 — desires ballooning, 通货膨胀 — monetary inflation, 人口膨胀 — population surge). The figurative sense often implies undesirable or uncontrolled growth.
