I am working on a "conlang", which is basically a fantasy language. I have collected 4,000-ish words in their "base" form (some we still need to find the base for, but they can be derived fairly easily based on the word's structure in the fantasy language). All these words are 1 syllable. I tried to collect words that capture the breadth and depth of knowledge, experience, and communication possibilities, and make those the 1 syllable words. Then I will have room for 130k 2 syllable words to handle more complex or specific concepts. But general concepts/words, there are about 4,000. Hopefully (well, the goal is), these 1 syllable words will capture the breadth and depth of human knowledge/experience. If not, I would like to find what I am missing and maybe trade some slots in the 1 syllable set for more important words.
Hence this question. Is there a database anywhere of "philosophical concepts" or concepts in general? Or something that at least covers all the concepts required to accurately represent the breadth and depth necessary to make sense of human experience on earth? That would be of great value in constructing a fantasy language lexicon, as I could make sure I have words for each specific concept.
