Wh-agreement

Wh-agreement is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wh-agreement rather than just read about it. In short: Wh-agreement refers to morphological changes triggered by wh-movement, usually in verbs or complementisers. It occurs in a number of Bantu languages, Austronesian languages including Chamorro and Palauan, Algonquin languages such as Ojibwe, as well as Hausa, French, Scottish Gaelic, and Irish.

Key takeaways

Wh-agreement belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Wh-agreement to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Wh-agreement from memory before moving on to harder problems.

Reference excerpt

Wh-agreement refers to morphological changes triggered by wh-movement, usually in verbs or complementisers. It occurs in a number of Bantu languages, Austronesian languages including Chamorro and Palauan, Algonquin languages such as Ojibwe, as well as Hausa, French, Scottish Gaelic, and Irish. For example, in Chamorro, the infix ⟨um⟩ (labelled ⟨WH[nom]⟩) is attached to the verb to mark agreement with the nominative question phrase following subject extraction:

Additionally, some languages have distinct agreement morphology depending on the case of element being moved. In the case of object extraction in Chamorro, the verb fa'gasi instead becomes fina’gasése (marked with ⟨WH[obj]⟩):

In French and Scottish Gaelic, special complementisers are used in cases of wh-movement:

Worked examples

Example 1 — a first encounter with Wh-agreement

Start with the simplest possible case. Write down what Wh-agreement claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wh-agreement before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wh-agreement ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wh-agreement

In research: Wh-agreement appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Wh-agreement in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Wh-agreement is common in secondary-school and first-year university syllabi. It links to neighbouring topics Linguistic morphology, so understanding it makes those chapters shorter.
In everyday life: Look for Wh-agreement outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Wh-agreement in simple terms?

Why does Wh-agreement matter?

Because it connects several science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Wh-agreement?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
