Virgate

Virgate 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 Virgate rather than just read about it. In short: The virgate, yardland, or yard of land (Latin: virgāta [terrae]) was an English unit of land. Primarily a measure of tax assessment rather than area, the virgate was usually (but not always) reckoned as 1⁄4 hide and notionally (but seldom exactly) equal to 30 acres.

Key takeaways

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

Reference excerpt

The virgate, yardland, or yard of land (Latin: virgāta [terrae]) was an English unit of land. Primarily a measure of tax assessment rather than area, the virgate was usually (but not always) reckoned as 1⁄4 hide and notionally (but seldom exactly) equal to 30 acres. It was equivalent to two of the Danelaw's oxgangs.

Name

The name derives from the Old English gyrd landes ("yard of land"), from “yard's” former meaning as a measuring stick employed in reckoning acres (cf. rod). The word is etymologically unrelated to the yard of land around a dwelling. "Virgate" is a much later retronym, anglicizing the yardland's latinized form virgāta after the advent of the yard rendered the original name ambiguous.

History The virgate was reckoned as the amount of land that a team of two oxen could plough in a single annual season. It was equivalent to a quarter of a hide, so was nominally thirty acres. In some parts of England, it was divided into four nooks (Middle English: noke; Medieval Latin: noca). Nooks were occasionally further divided into a farundel (Middle English: ferthendel; Old English: fēorþan dǣl, "fourth deal, fourth share"). The Danelaw equivalent of a virgate was two oxgangs or ‘bovates’. These were considered to represent the amount of land that could be worked in a single annual season by a single ox and therefore equated to half a virgate. As such, the oxgang represented a parallel division of the carucate.

Worked examples

Example 1 — a first encounter with Virgate

Start with the simplest possible case. Write down what Virgate 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 Virgate 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 Virgate 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 Virgate

In research: Virgate 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 Virgate 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: Virgate is common in secondary-school and first-year university syllabi. It links to neighbouring topics Obsolete units of measurement, Units of area, so understanding it makes those chapters shorter.
In everyday life: Look for Virgate 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 Virgate in simple terms?

Why does Virgate 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 Virgate?

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.
