International auxiliary language orthography

International auxiliary language orthography 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 International auxiliary language orthography rather than just read about it. In short: International auxiliary language orthography (IAL orthography) is often simplified when compared with natural language orthography. Script Most IALs use Latin script for their standard writing.

Key takeaways

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

Reference excerpt

International auxiliary language orthography (IAL orthography) is often simplified when compared with natural language orthography.

Script Most IALs use Latin script for their standard writing.

Letter inventory Most IAL writing systems use only letters from the ISO basic Latin alphabet, but there are some exceptions.

Volapük originally had three additional letters ꞛ, ꞝ, and ꞟ, devised by Schleyer himself. However, they have never been used much. They were replaced with vowels with Umlaut: ä, ö and ü. Volapük has no official method for avoiding the diacritic, but sometimes they are substituted with ay, oy and uy. This method is not used much, since the sequence oy occurs in "normal" Volapük, too. Esperanto has six letters with diacritics: ĉ, ĝ, ĥ, ĵ, ŝ, and ŭ. To avoid the diacritics, Esperanto offers two alternative orthographies. Uropi has ʒ. Universalglot has "œ", "σ" and "ü". Kotava uses accented á, é, í, ú in the 1st person singular of the verbal conjugation to express stress. These letters are not part of the official alphabet though.

Digraphs Although most IALs eschew digraphs, there are some IALs that use digraphs:

Interlingua: ch, qu, ph, sh Ido: ch, qu, sh Novial: ch, sh Esperanto H-system: ch (for ĉ), gh (for ĝ), hh (for ĥ), jh (for ĵ), and sh (for ŝ). X-system: cx (for ĉ), gx (for ĝ), hx (for ĥ), jx (for ĵ), sx (for ŝ), and ux (for ŭ). Slovio uses Esperanto's X-system as well: cx, gx, hx, sx, wx, zx.

Collation The basic ordering of the letters is as in the ISO basic Latin alphabet. Esperanto sorts each letter with diacritic mark directly after the corresponding letter without such a mark. Uropi sorts the non-ASCII ʒ after all ASCII letters, i.e. after z.

Worked examples

Example 1 — a first encounter with International auxiliary language orthography

Start with the simplest possible case. Write down what International auxiliary language orthography 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 International auxiliary language orthography 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 International auxiliary language orthography 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 International auxiliary language orthography

In research: International auxiliary language orthography 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 International auxiliary language orthography 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: International auxiliary language orthography is common in secondary-school and first-year university syllabi. It links to neighbouring topics International auxiliary languages, Orthography, so understanding it makes those chapters shorter.
In everyday life: Look for International auxiliary language orthography 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.
