缺口

• 拼音: quē kǒu
• 汉字拆解: 缺 = 缶 + 夬 (jar + missing piece — a container with a piece gone); 口 = 口 (opening/mouth)

含义

A gap, breach, or notch; a missing section in something. Figuratively: a shortfall or deficit between supply and demand or between what is needed and what is available.

In infrastructure and engineering, refers to a physical breach (e.g. in a wall, levee, or blade). In economics and planning, refers to a supply-demand shortfall. 填补缺口 (fill the gap) is a common phrase across both literal and figurative senses.
