Hebrew grammar is partly analytic, expressing such forms as dative, ablative, and accusative using prepositional particles rather than grammatical cases. However, inflection plays a decisive role in the formation of the verbs and nouns. E.g. nouns have a construct state, called "smikhut", to denote the relationship of "belonging to": this is the converse of the genitive case of more inflected languages. Words in smikhut are often combined with hyphens. In modern speech, the use of the construct is sometimes interchangeable with the preposition "shel", meaning "of". There are many cases, however, where older declined forms are retained (especially in idiomatic expressions and the like), and "person"-enclitics are widely used to "decline" prepositions.
