In addition to syntactic description through ten classes of complements, each complement is also described morphologically. E-Glava regards morphology as the realization of syntax. We introduced morphological description in our model because we think that for the usage of Croatian, which has a fully-fledged case system, it is essential to precisely define which morphological case have to be used in certain syntactic position with specific verb. Hence, we think that generalized system of syntactic complements does not yield the complete valency description of Croatian verbs. It is defined that syntactic (valency) complements are realized by four major morphological categories and a number of subcategories. The major morphological categories needed to morphologically describe Croatian syntactic complements are (1) prepositions, (2) cases, (3) sentential realizations, and (4) other. The category of prepositions (1) includes all Croatian prepositions, which amounts to 199. The category of cases (2) includes all Croatian morphological cases (nominative, genitive, dative, accusative, instrumental, and locative) except for the vocative case, which is never realized on verbal arguments – it is always an independent phrase. The category of sentential realizations (3) contains the Croatian conjunctions (da, što, kako, gdje, li, WH-word, neka, kao+) and other elements by which a sentence can be introduced next to a verb (quotes and the zero conjunction). Quotes (marked with the word Navod) and the zero conjunction (0) are listed alongside conjunctions. The fourth morphological category (other) includes (4.a.) adverbs and adverbial phrases, (4.b.) the infinitive, (4.c.) kao-phrase, (4.d.) quantificational phrases, and (4.e.) adjectives. As is apparent from the list above, morphological categories are not distributed in any meaningful way, but by functional principle. Some morphological realizations are mainly typical for some complements: kao-phrase and adjectives are frequently realizations of predicative complements.
