This article analyzes the relationship that exists between the qatal and wayyiqtol forms in Biblical Hebrew. It provides a twofold approach, based on complexity theory, fuzziology, cognitive linguistics and the theory of dynamic semantic maps, on the one hand, as well as on an original empirical study involving all the instances of the two grams in the book of Genesis, on the other. As a result, the article advances a model of an intricate, multi-level and dynamic interaction of qatal and wayyiqtol in terms of two kinetic waves that spread along a grammaticalization channel recursively used in the language—in this case, the resultative stream.
