危害 (wēihài) - use 危及 when emphasizing the immediate threat to safety, while 危害 focuses more on the harm or damage caused.

Think of 危 (wēi) as a 'danger sign' with its sharp edges, while 及 (jí) resembles reaching out. Together, imagine a danger sign reaching out to grab someone—this helps you remember that 危及 means to endanger or jeopardize.

Learners often confuse 危及 with similar terms like 危险 (wēixiǎn) which means 'danger' itself. 危及 is typically used in more formal contexts, such as news reports or official documents, rather than in everyday conversation. Be cautious with the tones; using the wrong tone can change the meaning entirely.

While 危及 is not part of the official HSK vocabulary, it can be useful for learners at HSK Level 5 and above when discussing topics related to safety and security. Focus on understanding how it is used in compound phrases and its relation to other words like 危险.

In Chinese culture, the concept of danger is often linked to collective safety, especially in discussions around natural disasters or public health crises, where the implications of 危及 can extend beyond individual safety to societal well-being.

Learners might mistakenly use 危及 in contexts where 危险 would be more appropriate, such as saying '这件事情很危及' (This matter is very endangering) instead of '这件事情很危险' (This matter is very dangerous). Always ensure you are using the correct term based on the context.
