迟到 (chídào, to be late) — use 赶不上 when emphasizing inability to keep pace, while 迟到 focuses on arrival time.

Imagine a runner who is trying to catch up with others in a race but keeps falling behind. The character 赶 (gǎn) looks like a person running, and 上 (shàng) indicates going up, suggesting the effort to reach the same level or position.

This phrase can be used in both formal and informal contexts, such as discussing academic performance or work deadlines. A common mistake is to confuse 赶不上 with 追上 (zhuī shàng), which means 'to catch up', instead of indicating inability.

While 赶不上 is not part of the official HSK vocabulary list, it is useful for learners at HSK 4, where they encounter phrases discussing progress and competition. Focus on its use in sentences to express limitations in achieving goals.

In Chinese education and work culture, the concept of competition is prevalent, and 赶不上 can reflect the pressure individuals feel to keep up with peers, especially in high-stakes environments like exams or career advancement.

Learners might mistakenly say 赶得上 (gǎn de shàng), suggesting they can catch up, which is the opposite of the intended meaning. The correct usage is 赶不上 to indicate they cannot keep up.
