===== Core Meaning =====
  * **Pinyin (with tone marks):** yī shí èr niǎo
  * **Part of Speech:** Chengyu (成语) - A four-character Chinese idiom, often with a classical origin.
  * **HSK Level:** N/A (but extremely common and widely understood by all native speakers).
  * **Concise Definition:** To accomplish two objectives with a single effort.
  * **In a Nutshell:** Imagine having two tasks and finding a single, clever solution that completes both at the same time. That's the essence of 一石二鸟. It's used to praise a smart plan or an efficient action that brings multiple benefits. The feeling is one of satisfaction, cleverness, and high efficiency.
===== Character Breakdown =====
  * **一 (yī):** The number one; a single.
  * **石 (shí):** Stone or rock.
  * **二 (èr):** The number two.
  * **鸟 (niǎo):** Bird.
These characters combine to create a very literal and visual image: using a single stone to hit two birds. Unlike many other Chengyu, the literal meaning here directly maps to its figurative meaning, making it one of the easiest idioms for learners to remember.
===== Cultural Context and Significance =====
The concept of achieving maximum results with minimum effort is universally valued, but **一石二鸟** taps into a deep cultural appreciation for cleverness (聪明 - cōngmíng) and strategic thinking in China. Its origin is often attributed to a story from the //History of the Northern Dynasties// (《北史》). In the story, a skilled archer named Changsun Sheng (长孙晟) was challenged to prove his abilities. Seeing two vultures fighting over a piece of meat in the sky, he fired a single arrow, striking and killing both birds at once. This feat not only demonstrated his archery skill but also his strategic mind—waiting for the perfect moment of opportunity.
While its English equivalent, "kill two birds with one stone," is a perfect functional match, the use of Chengyu like **一石二鸟** in Chinese speech and writing often carries a slightly more literary and educated weight. Using it correctly demonstrates a deeper understanding of the language and culture beyond just basic vocabulary. It celebrates the "smart" solution over the "brute force" solution.

===== Nuances and Common Mistakes =====
  * **Not a "False Friend":** This is a rare case where the Chinese idiom and its English equivalent are almost perfect matches in meaning and usage. The risk of misunderstanding is very low.
  * **Overuse:** The most common mistake for learners is overuse. Like any idiom, dropping **一石二鸟** into every other sentence will sound unnatural and forced. Use it when you genuinely want to emphasize the dual-benefit and cleverness of an action.
  * **Context is Key:** While it's a positive term, ensure the two "birds" you're referring to are clear from the context. Just saying "**一石二鸟**" without the surrounding explanation can be confusing.
  * **Cultural Note on "Killing":** While some modern English speakers are moving towards gentler alternatives like "feeding two birds with one scone," the Chinese **一石二鸟** does not carry a negative or violent connotation. It is perceived through the lens of the historical story, focusing on skill, precision, and strategy rather than animal cruelty.
