Summary: Learn the Chinese word 假说 (jiǎshuō), the direct equivalent of “hypothesis” or “conjecture.” Primarily used in scientific, academic, and formal logical reasoning, a `假说` is a proposed explanation for a phenomenon that has not yet been proven. This page breaks down its meaning, cultural context, and practical usage, showing you how to distinguish it from related concepts like “theory” (理论) and “guess” (猜想) with over 10 clear example sentences.

Pinyin (with tone marks): jiǎshuō

Part of Speech: Noun

HSK Level: HSK 6

Concise Definition: An unproven proposition or supposition put forward as a basis for reasoning or further investigation.

In a Nutshell: `假说` is the essential starting point for discovery. Think of it as a formal, educated “what if?” statement used by scientists, researchers, and detectives. It isn't just a random guess; it's a carefully constructed idea based on initial observations, designed to be tested. It's the step you take *before* you can arrive at a full-fledged “theory.”

假 (jiǎ): While this character most commonly means “fake” or “false,” in this context it takes on a more classical meaning of “to suppose” or “to borrow.” Think of it as “provisional” or “supposed,” indicating that the idea is temporary and not yet confirmed as fact.

说 (shuō): This character simply means “to say,” “to explain,” or a “statement/saying.”

The two characters combine to literally mean a “provisional statement” or “supposed explanation.” This beautifully captures the essence of a hypothesis: an idea put forth for discussion and testing, which may or may not turn out to be true.

The term `假说` is not deeply rooted in ancient Chinese philosophy but is instead a key component of modern, globalized intellectual and scientific discourse in China. Its widespread use reflects the adoption and integration of the Western scientific method into Chinese education and research since the 20th century.

Unlike culturally specific terms like `关系` (guānxi), `假说` has a nearly one-to-one correspondence with the Western concept of “hypothesis.” Its significance lies in its role as a universal tool for logical inquiry, critical thinking, and innovation in modern China.

In a learning environment, distinguishing between a `假说` (an unproven idea), a `观点` (guāndiǎn, a personal opinion), and a `理论` (lǐlùn, a well-supported theory) is seen as a hallmark of rigorous, logical thinking. This distinction is heavily emphasized in higher education and scientific fields.

Formal and Academic Contexts: This is the primary home for `假说`. You will hear and read it constantly in university lectures, scientific papers, academic conferences, and documentaries. It is standard vocabulary for any discussion involving research, experimentation, or formal logic.

Formality: `假说` is a formal, technical term. Using it in a casual conversation would sound overly academic and out of place. For instance, you wouldn't use it to guess why a friend is running late; for that, you'd simply use `我猜` (wǒ cāi - I guess).

Connotation: The term is entirely neutral. It carries no inherent positive or negative weight. It is simply a label for a specific step in the process of investigation and discovery. A `假说` is not a “bad” thing for being unproven; its entire purpose is to be tested.
