试验

The word 试验 (shì yàn) is a fascinating term that sits right at the intersection of curiosity and science. At its core, it means to test or to experiment. Think of it as the moment you decide to stop guessing and start proving.

When you use this word, you are usually talking about a structured attempt to find an answer. Whether you are a scientist in a lab or a student trying to see if a paper airplane flies better with wings, you are performing a 试验. It is not just a random guess; it is a purposeful action taken to gather data or experience.

In daily life, it implies a sense of rigor. It suggests that you have a plan, you are watching the results closely, and you are ready to learn from the outcome. It is a very active word that invites discovery and improvement.

The etymology of 试验 is deeply rooted in the history of Chinese characters. The character 试 (shì) comes from the radical for 'speech' (言) and the phonetic component 'shì', originally implying a trial or an examination of words or abilities. It evolved to mean 'to test' or 'to try out'.

The second character, 验 (yàn), also features the 'speech' radical, but its right side represents a seal or a mark of verification. Historically, it referred to checking the truth or validity of something—essentially, 'verifying' or 'proving'.

Together, these characters create a powerful compound that represents the marriage of trial (试) and verification (验). While the individual characters have ancient roots dating back to Oracle Bone script, their combination as a standard term for 'experiment' became solidified in modern Chinese as scientific inquiry became a global standard. It reflects a cultural transition from philosophical inquiry to empirical, evidence-based science.

Using 试验 correctly depends on the formality of your situation. You will most often hear this in academic, scientific, or industrial settings. It is the go-to word for 'conducting an experiment'.

Common collocations include 进行试验 (to conduct a test) or 试验数据 (test data). If you are talking about a product, you might say 产品试验 (product testing). It is a formal word, so you wouldn't use it to describe trying on a pair of shoes—for that, you would use 试穿.

The register is definitely on the formal side. If you are writing a report or giving a presentation, 试验 is your best friend. In very casual, everyday conversation, people might sometimes use simpler alternatives, but 试验 remains the standard for any situation involving a process or a scientific goal.

While 试验 is a technical term, it appears in several fixed expressions that highlight its importance in life and work. 1. 试验田 (Experimental field): A place where new ideas are tested. 2. 以身试验 (To experiment on oneself): Used when someone takes a big risk to prove a point. 3. 试验阶段 (Testing phase): The period where a project is being refined. 4. 反复试验 (Trial and error): The classic method of learning through failure. 5. 临床试验 (Clinical trial): A critical term in medical science for testing new drugs.

Grammatically, 试验 functions primarily as a verb or a noun. As a verb, it is often paired with the auxiliary verb 进行 (to conduct). For example, 进行试验 is a very common structure.

Pronunciation-wise, it is shì yàn. The first character shì is a fourth-tone sound, sharp and falling. The second character yàn is also a fourth tone. This double fourth-tone combination gives the word a very decisive, punchy sound.

It is not a countable noun in the English sense, but in Chinese, you can use measure words like 次 (cì) to count the number of tests: 一次试验 (one test). It does not have plural forms, as Chinese nouns do not change based on number.
