Releases β 1.3.3


This website is in the beta phase of development, meaning that it's currently being worked on. We have decided to make Allo available to the public during all development phases. The website may not contain all planned features and services. Many features may be incomplete, which can hinder user experience and reliability.

You can expect the following:

  • Minor bugs
  • Minor downtime
  • Ongoing testing and rapid feature release cycles
  • Missing data
  • Average load times

If you are doing academic or scholarly research, it is safe to rely on the accuracy of our data.

Version β 1.3.3 What's this?




We're providing modern and user-friendly dictionary interfaces for dead ancient languages.

Many languages designated as retired (dead) are still important for a variety of reasons (spiritual, scientific, etc.). We're providing the latest tools, resources, and technologies so that more people can have access to them. For each language, we include the top 1,000 highest-frequency words alongside other valuable information related to word frequency, grammar, pronunciations, and example sentences.


One entry at a time.

Languages are complicated cultural products, so it takes time to organize them. We are slowly adding new features, datum points, and entries on a weekly basis.

Information about the Allo project.

Who Allo was created by Boban Dedović, a Croatian-American psycholinguist and technologist. The project is currently managed under the auspices of the OMNIKA Foundation, a Nevada-based 501(c)(3) nonprofit dedicated to digitizing and making freely available all the world's mythological contents. The main sponsor of this research project is the Consciousness Research Society (CRS).
What The Allo website is a modern dictionary platform for dead ancient languages like Latin, Sumerian, and others.
When The Allo website was initially designed and created by Boban Dedović in 2019. Since 2020, it has been managed by the OMNIKA Foundation.
Where The main contributors of Allo are from the United States, although volunteers and experts are contributing remotely from around the world. The OMNIKA Foundation is a 501(c)(3) nonprofit based in Las Vegas, Nevada, USA.
Why Allo was built because there was no other online tool that offered comprehensive, credible, and well-cited information on dead ancient languages in an easy-to-use format.



Project history.

In March 2019, a group of researchers at the CRS were interested in studying ancient languages to see how words evolved over time (and across cultures). The project was formally announced in April 2019 and the alpha version was soft-launched in August of the same year.

In March 2020, the alpha version of Allo became available to the general public. Read announcement

In February 2023, the beta version was released in tandem with the completion of our first language–Allo Latin.

On June 2, 2023, the Allo dictionary platform was presented at the 24th biennial conference of the Dictionary Society of North America at the University of Colorado, Boulder, in Boulder, Colorado, USA. The conference abstract is available in the OMNIKA Library and a full video of the presentation is available on YouTube.

On June 22, 2023, Allo changed its domain name from to


What does Allo mean?

Allo is an acronym that stands for Ancient Language Lexical Ossuary. An ossuary is a box or place where ancient people used to store the remains of the deceased. Allo is thus a digital ossuary for dead ancient languages.

The symbol is represented by two wedge marks that resemble the syllabic sign for "A" in the Sumerian language and Sumero-Akkadian cuneiform script. Cuneiform is one of the world's oldest writing systems.


#1 Free

Free for all—all for free.

Allo is a nonprofit research project that shares everything with the world and doesn't charge a fee. We also do not run advertisements.

#2 Credible

Citations are required.

Almost all information in our index has citations and references to where the information came from. This includes direct links or original source material wherever possible.

#3 Inclusive

Made for normal people.

Linguistics is a complicated subject matter, and this alienates a lot of people that are interested in studying it. The aim of our project is to make this rich information as easy to access as possible. We try to do this by building tools and resources that normal people can use. For example, all pages are mobile friendly, which is not always easy to integrate with tables or text-heavy content.
