Ol Onal

Ol Onal 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 Ol Onal rather than just read about it. In short: The Ol Onal, also known as Bhumij Lipi or Bhumij Onal, is an alphabetic writing system for the Bhumij language. Ol Onal script was created between 1981 and 1992 by Ol Guru Mahendra Nath Sardar.

Key takeaways

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

Reference excerpt

The Ol Onal, also known as Bhumij Lipi or Bhumij Onal, is an alphabetic writing system for the Bhumij language. Ol Onal script was created between 1981 and 1992 by Ol Guru Mahendra Nath Sardar. Ol Onal script is used to write the Bhumij language in some parts of West Bengal, Jharkhand, Orissa, and Assam.

Language

Bhumij is a language of the North Munda group of the Austroasiatic languages, spoken mainly in the Indian states of Jharkhand, Odisha and West Bengal. It is spoken by around 100,000 people in India. The language is closely related to Mundari (mutually intelligible with it but with many dialectal differences), Ho, and Santali.

History The Bhumij community had no written language, and knowledge was transmitted orally from one generation to another. Later researchers started to use Devanagari, Bengali, and Odia scripts to document the Bhumij language. However, Bhumijs did not have their own script. The Ol Onal script was created in between 1981 and 1992 by Mahendra Nath Sardar for writing Bhumij in India. It was initially designed by Sardar as a bicameral script, where the lowercase letters were known as Galang Onal, however only the capital letters called Ol Onal have been used for teaching and printed books. Sardar wrote many text books in the script (using only Ol Onal capital letters), but there's no known record of Sardar's Galang Onal lowercase letters (which are very different from the taught capitals) ever being used in publications, except in the script author's personal design manuscripts, with various tried variants that Sardar did not promote for wide use in the Bhumij community.

Structure Ol Onal is written from left to right and behaves as a regular alphabet, and not like the typical abugidas used for other Indic scripts: the 6 basic vowels and 24 basic consonants are simply written as standalone letters, and the consonants do not have any inherent vowel. So there's no vowel killer (or halant) and no need to form complex clusters or to contextually change the letter forms in ligatures for initial or grouped vowels, and final or grouped consonants. (The Ol Chiki alphabet has a similar structure). There are three additional signs (referred to as ṭiḍaḥ): the nasalisation sign mu (or mun arang [˜], a dot diacritic used above vowel letters), the lengthening sign ikir (or ikir arang [ː], a dot diacritic used only below the vowel letter a [ɔ], where it can occur simultaneously with the nasalisation sign mu), and hoddond (a special sign occurring only after the consonant letters ab [b] and uj [ʤ] to indicate glottalisation [ɒ]). The script also includes ten decimal digits, and an additional abbreviation sign (a small ring above the baseline, at the middle height of letters and digits).

Letters Ol Onal consists of 30 letters, including 6 basic vowels and 24 basic consonants.

Numerals Ol Onal has its own set of decimal digits (0–9) that function identically to standard Western numerals.

The original digit designs differed in form; however, when the first digital fonts were developed in 2013, these shapes were modified due to technical limitations in accurately rendering the original designs.

Unicode

Ol Onal was added to the Unicode Standard in September, 2024 with the release of version 16.0. The Unicode block for Ol Onal is U+1E5D0–U+1E5FF:

Worked examples

Example 1 — a first encounter with Ol Onal

Start with the simplest possible case. Write down what Ol Onal 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 Ol Onal 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 Ol Onal 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 Ol Onal

In research
Ol Onal 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 Ol Onal 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
Ol Onal is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alphabet stubs, Alphabets, Austroasiatic language stubs, so understanding it makes those chapters shorter.
In everyday life
Look for Ol Onal 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 Ol Onal in simple terms?

The Ol Onal, also known as Bhumij Lipi or Bhumij Onal, is an alphabetic writing system for the Bhumij language. Ol Onal script was created between 1981 and 1992 by Ol Guru Mahendra Nath Sardar.

Why does Ol Onal matter?
