Logeion

Logeion is a computer 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 Logeion rather than just read about it. In short: Logeion is an open-access database of Latin and Ancient Greek dictionaries. Developed by Josh Goldenberg and Matt Shanahan in 2011, it is hosted by the University of Chicago.

Key takeaways

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

Reference excerpt

Logeion is an open-access database of Latin and Ancient Greek dictionaries. Developed by Josh Goldenberg and Matt Shanahan in 2011, it is hosted by the University of Chicago. Apart from simultaneous search capabilities across different dictionaries and reference works, Logeion offers access to frequency and collocation data from the Perseus Project.

Features Having started out as an aggregator for Latin and Ancient Greek dictionaries, Logeion has implemented multiple new features in its development. These include:

the integration of reference works on antiquity; frequency and collocation data from the Perseus Project; corpus examples, equally retrieved from the Perseus Project; references to relevant chapters in a number of (English-language) textbooks. Furthermore, an iOS app was developed by Joshua Day in 2013. The app's second version, launched in 2018, is also available for Android devices.

Dictionaries As of June 2026, Logeion contains the following dictionaries.

Worked examples

Example 1 — a first encounter with Logeion

Start with the simplest possible case. Write down what Logeion claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer 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 Logeion 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 Logeion 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 Logeion

In research: Logeion appears in computer 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 Logeion 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: Logeion is common in secondary-school and first-year university syllabi. It links to neighbouring topics Computing in classical studies, Digital humanities, Online databases, so understanding it makes those chapters shorter.
In everyday life: Look for Logeion 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.
