В нашем меморандуме говорится, что славянские языки находятся в относительно когерентной языковой группе. Знание одного славянского языка обычно достаточно, чтобы приблизительно понять о том, что написано в тексте в любом другом славянском языке. За всю историю, этот факт вдохновил лингвистов и других людей создать всеобщий славянский язык, понимаемый всеми славянами, включая известный старославянский язык 9-ого века, развитый двумя византийскими греческими миссионерами, братьями Константином (Кириллом) и Мефодием из Салоник, совместными святыми Европы, а также десятки других проектов 16-ого века. В них есть одна общая черта: все они основаны на предложении, что славянские языки достаточно похожи друг на друга, чтобы сделать такой вспомогательный язык вообще возможным.

Our memorandum says, that the Slavic languages are a relatively coherent language group. Knowledge of one Slavic language is often sufficient to get at least a rough understanding of what a text in any other Slavic language is about. During the course of history, this fact has inspired linguists and others to build a universal Slavic language that would be understandable for all Slavs, including the famous Old Church Slavonic language from the 9th century developed by two Byzantine Greek missionaries and brothers Konstantinos (Cyril) and Methodios from Salonica, the co-patrons saints of the Europe, as well as dozens of other projects from the 16th century onwards. What they have in common is that they are all based on the assumption that the Slavic languages are similar enough to make such an auxiliary language possible at all. 

Neoslavonic language design is based on the harmony of following three principles:

1. To share grammar and common vocabulary with modern spoken Slavic languages in order to build a universal language that Slavic people can understand without any prior learning.
   
   
2. To be an easy-learned language for those who want to use this language actively. Non-Slavic people can use this language as the door to the big Slavic world. We believe, that knowledge of NS enables both Slavic and non-Slavic people greater passive (e.g. receptive) understanding and better learning of the living Slavic languages.
   
   
3. Neoslavonic continues the tradition of the Old Church Slavonic language (OCS). OCS was the first literary Slavic language, believed to have been artificially developed in the 9th century by two Byzantine Greek missionaries Saints Kyrillos and Methodios, who were credited with standardizing the Slavic dialects and were using it for translating the Bible and other ecclesiastical texts as the tool of the Christianisation of the Slavic people. OCS is still frequently used by the Orthodox Church and sometimes also by the Roman-Catholics in many Slavic countries up to the present days. NS is designed as the modernized and simplified but still sufficiently compatible version of this language.  

Why do we need an artificial Slavic language?

We know that one half (maybe yet more) of the total number of Slav-speaking people has Russian language. If the Russian language would be sufficiently simple and understandable to other Slavs without learning, our project would be unnecessary. Unfortunately it is not. Russian is far from the imaginary linguistic center of Slavic languages. It has a specific alphabet, phonetics, grammar and vocabulary without the universal Slavic validity. The very similar situation we have in all modern Slavic languages, above all in other candidates for the universal Slavic language (e.g. Polish).
