 Another significant difference between dictionaries produced up to Kaspi’s time and Sharshoth Kesef is the order of discussion of lexical forms. Both Ibn Janaḥ and Radaq, who preceded Kaspi, begin by presenting the forms of the verbs derived from a given Biblical root, to be followed by the noun forms. Unlike earlier Hebrew and Arabic lexicographers, Kaspi composed a dictionary in which the nouns derived from the root were described first and the relevant verb form system was only shown thereafter. This change in order is by no means coincidental. In Retuqot Kesef, Section 40, Kaspi analyzes the structure of the Hebrew language: First, its founders agreed about the general meaning of each root. They then coined an abstract name designating this meaning that is not connected to any particular object or occurrence. Subsequently, they coined the infinitive of the verb, thereby creating the reality to which the noun refers: The infinitive is an abstract noun expressing an occurrence. Thereafter, they formed adjectives, that are concretely connected with specific objects. After completing the nouns, they invented the system that addresses tangible activity and occurrences. In other words, Kaspi maintains that the formation of nouns and the various weights accorded them proceeds from the most abstract to the most tangible. As the verb system is most tangible of all, it was devised last.
