A. is incorporating (it combines subject with intrinsic attributes), agglutinating (prefficial-sufficial, grammatical categories are expressed using prefixes and/or suffixes as morphems) and composing (it creates new words mostly of existing stems) language. Words are created of roots (lexems), carrying the general meaning (e.g. ront) and of determinatives (morphems), which serve to express grammatical qualities (e.g. la, o, u).
Root, modified with determinative, becomes base for further derivation, stem, or creates meaningful ensemble - word (monem, e.g. dog - ronto, puppies - larontuo).
Basic part of speech, subject, is created using connection of several stems, having thus included other, directly not expressed, parts of speech (dog - ronto /subject/, our white dog - rontokinva /subject + intrinsic attributes/). Lexicological, and also morphological, changes and shifts are ruled by one and the same principle.
A. knows three basic word types: autosemantics (nouns, verbs), independent in meaning creating clause components, synsemantics (conjunctions, determinatives), words dependent in meaning by connection with autosemantics, and vicesemantics (pronouns, adverbs, interjections), which substitute autosemantics, but their role is not to name.
