遗言 (yíyán) refers to the last words or messages spoken by a person before death, while 遗嘱 (yízhǔ) is a formal legal document regarding the distribution of possessions. Use 遗嘱 when discussing legally binding instructions, and 遗言 for spoken farewell messages.

Imagine someone writing their last will under a tree (树, shù). The character 遗 combines 'to leave behind' (遗) and 'will' (嘱), suggesting a legacy left under a mighty tree for future generations.

Be mindful of the formal nature of this term; it is typically used in legal and serious discussions. Common collocations include 遗嘱公证 (notarized will) and 遗嘱效力 (validity of a will). Avoid using this term in casual conversation.

Though not part of the standard HSK vocabulary, understanding 遗嘱 helps learners grasp concepts related to legal and familial obligations. Focus on recognizing its components and related terms like 遗产 (inheritance) to build vocabulary around this topic.

In Chinese culture, discussing wills and inheritance can be sensitive, often seen as inviting bad luck. However, having a will is increasingly recognized as important for ensuring peace within families after a loved one's passing.

Learners often confuse 遗嘱 with similar terms like 遗产. For example, saying '我有一个遗产' (I have a will) is incorrect; the correct term is '我有一个遗嘱'.
