So, I've started adding some basic root words to my conlang (which now has a name by the way, it's called Tamuni). I've encountered a problem, however. I thought it logical to start by creating some simple, one-syllable root words to convey simpler concepts, and create derivations and more complicated words later. However, a problem quickly arose: My language, being roughly modeled off of Polynesian languages, has a very restrictive syllable structure and phonetic inventory. There are only 11 consonants (excluding the glottal stop, which words cannot start with), and 8 vowel sounds (including dipthongs.) The syllable structure is (C)(C)V, but the only allowed pairs are tr, kr, fr, kl, and fl, so when you do the math, this comes up with only 136 possible single-syllable words. Although that is a decent amount, it's certainly not enough to convey all the different simple meanings that I would want. Then, there's also the fact that single-syllable words are probably likely to have a more grammatical function, and that if every single one of those single-syllable words had a meaning, then longer words could be somewhat confusing, as they might seem to be combinations of two root words, when they're really not at all. So, how many simple, non-grammatical root words should I roughly aim for? What kinds of meanings should they be assigned to?
