Distinction between Paradigms and Syntagms
IEML’s grammar is completely regular. It can be conveniently divided into two main aspects: a paradigmatic organization and a syntagmatic organization.
In linguistics, a paradigm is a group of units playing a similar role in the same language. For instance, most languages include paradigms for economic actions (buy, sell, lend, repay…), or colours (red, blue, yellow…). In a given expression, you can replace one word by another word of the same paradigm and still get a meaningful sentence. In IEML, semantic paradigms are mirrored by paradigms at the level of signifiers. For example, all the names for colours have the same signifier structure, which is not the case in natural languages. This parallelism is commented on specific examples in this page.
By contrast, a syntagm is a sequence of units of the same expression. In the two following sentences: « The gazelle smells the presence of the lion » and « The lion smells the presence of the gazelle », the set of words are identical but the words « gazelle » and « lion » do not share the same grammatical role. Since those words are inverse in the syntagmatic structure, the sentences have distinct meanings.
IEML’s Paradigmatic Organization
In IEML, the words of the dictionary are constructed in a very regular way and are regrouped in root-paradigms. Any word is a member of one root paradigm and only one. Root paradigms themselves contain several recursively intertwined sub-paradigms. There are not only paradigms for words, but also at higher levels of complexity: phrases and texts. IEML paradigms are represented by tables where each row and each column is identified by a specific constant. You can find more on IEML paradigms here.
IEML’s Syntagmatic Organization
A sentence may contain nine distinct roles, including: verbs, subjects, objects, recipients, times, places, manners, etc.
Distinction between proper names et common nouns
Common nouns are signifiers whose meanings are general categories (signified). By contrast, proper names are signifiers pointing to individual referents. Everything is nicely explained here.
