Although the revivers of Hebrew tried to base the spoken language on the grammar of Hebrew classical periods, the phonetic and grammatical structure of Modern Hebrew shows divergence from it due to various factors. There are three tenses and one mood in the verb.
Nouns are either masculine or feminine.
Person inflection in the verbs is obligatory, and so is preposition inflection. Modern Hebrew is an SVO language with an alternating VSO word order that was dominant in classical Hebrew. Topicalization and other word order shifts are possible. Adjectives follow head nouns, but numeral quantifiers precede them. Copulative verbs are obligatory in the past or the future tense.
