贯通

• Pinyin: guàn tōng
• Hanzi breakdown: 贯 = 毌 + 贝 (penetrate); 通 = 辶 + 甬 (pass through unobstructed)

Meaning

To link through; to achieve thorough understanding; to connect seamlessly. Describes either physical connectivity (two tunnels meeting) or intellectual mastery (understanding a subject completely).

Appears in both infrastructure contexts (两线贯通 — two lines connected) and intellectual ones (融会贯通 — integrate knowledge into a coherent whole). The compound 融会贯通 is one of the most common four-character expressions for deep, holistic mastery.

Examples

1. 隧道两端的施工队伍终于在深夜完成了贯通作业。 The construction teams at both ends of the tunnel finally completed the breakthrough late at night.
2. 学习语言不仅要记忆词汇，更要融会贯通地运用。 When learning a language, it's not enough to memorize vocabulary—you need to integrate it and use it flexibly.
