I need some help with bibliography to fill some topics that a need for my project.
Im trying to create a pure a priori language where phonetic and syllable are linked to the meaning of the roots of the words, and the syntactic sense (so words are some kind of image of the meaning).
I know something of Esperanto and Toki pona but I have a problem here, and this the reason why I opened this question: I need some bibliography about the most simple grammars and, specially, I need some bibliography about the most basic vocabulary some that language must have.
Im trying to start from the basics: needs and relationships of humans, and going to more abstract things as time, space, quantitative, qualitative, relational or types of things.
