How stable is Globasa at this point? Is it safe to start learning it without the prospect of having to relearn words and grammar through on-going revisions?
Yes, Globasa is actually quite stable and ready to be put into practice. The core of the language is complete, and includes all function words. However, minor revisions that don’t disrupt the core of the language are certainly possible in the coming months. The introduction of upper-case letters, for example, has been one such revision. It doesn’t disrupt the language itself. There might be other minor revisions to the content words, or even to the grammar details, but not the function words.
Beyond minor modifications, there is plenty of further development that the language will require, with everybody's help, including: adding more root words, adding more conventionalized affixed words and “compound words”, fine-tuning the grammar details. Anything that disrupts the core, particularly the function words and affixes, is not worth modifying.
Why not be open to revising the core? I think the answer is obvious. It’s a trap, for two reasons. First, anything that disrupts the core is a bad idea because as soon as a modification is made to the core, it necessitates other adjustments, which in turn require other changes, and so on. And second, this would then invite people to insist on other revisions, which would lead to revision after revision, with the result being that it would take years and years before we could safely start learning the language.
Everybody has their own opinions on what a worldlang should look like, but the reality is that a perfect language doesn’t exist. It cannot satisfy every idea that every person has. So once the complete core of a worldlang has been built, the only modifications that would be worth making would be anything that’s an actual flaw in the design, objectively speaking, something that prevents the language from actually working, or possibly, anything that’s counter to its own internal principles.
As a linguist and language instructor, I can assure you that there are no such flaws in Globasa’s design. It’s not perfect because a perfect language is impossible, but I did spend countless hours of hard and meticulous work going round and round, testing and retesting, making revision after revision, until I could be certain that the language works and that it is, at least to the best of my ability, as easy as possible to learn for the average human.
So as the Globasa community learns the language, there might be a content word (nouns/verbs, adjective/adverbs) here and there that may absolutely need to be either slightly modified or changed altogether to a different root. Even this is very unlikely, as I’ve reviewed the dictionary countless times, making such necessary revisions. As we move forward, the language will continue to develop primarily through additions, rather than through alterations.
