L'ewa is a analytic language. Every single word has only one form and particles are used to modify the meaning or significance of words. There are only two word classes: content and particles.
L'ewa is a nominative-accusative language. Other particles may be introduced in the future to help denote the relations that exist in other alignments, but I don't need them yet.
As said before, L'ewa only has two word classes, content (or verbs) and particles to modify the significance or relations between content. There is also a hard limit of two arguments per verb, which should help avoid the problems that Lojban has with its inconsistent usage of the x3, x4 and x5 places.
As the content words are all technically verbs, there is no real need for a copula. The ka/ke/ku series can also help to break out of other things that modify "noun-phrases" (when those things exist). There are also no nouns, adjectives or adverbs, because analytically combining words completely replaces the need for them.
Nouns and verbs do not inflect for numbers. If numbers are needed they can be provided, otherwise the default is to assume "one or more".
