驱赶 (qūgǎn) - use 驱逐 when the removal is more authoritative or formal, whereas 驱赶 implies driving away, often with less formality.

Imagine a 'crew' (sounds like 'qu') pushing someone out of a 'zoo' (sounds like 'zhu'), symbolizing the act of expelling someone from a place. Visualize a group of people forcing an unwanted guest out of a party, reinforcing the meaning of removal.

Be careful not to confuse 驱逐 with similar terms like 赶走 (gǎnzǒu), which means to chase away and is less formal. This term is more suitable for formal contexts, such as legal or governmental discussions. Remember that 驱逐 is often used with a direct object, such as 驱逐出境 (qūzhú chūjìng) meaning 'deport'.

As an HSK Level 6 word, 驱逐 connects with other words related to legal actions and authority. Students should focus on its formal usage and related phrases, such as 驱逐令 (qūzhú lìng), meaning 'expulsion order'.

In Chinese history, expulsion has been a significant theme, especially during periods of political strife and social upheaval. The term is often associated with governmental actions, such as the expulsion of immigrants or dissidents during certain historical events.

Learners often mistakenly use 驱逐 in informal settings, where lighter terms like 赶走 are more appropriate. For example, saying '我把他驱逐了' (Wǒ bǎ tā qūzhú le) might sound overly formal when talking about a friend leaving a gathering.
