Modern English has largely abandoned the inflective case system of the Indo-European in favour of analytical construction. Personal pronouns more firmly retain morphological cases than any other word class (the legacy of Old English's broader Germanic case system). For other pronouns, and for all nouns, adjectives, and articles, grammatical function is indicated only by word order, preposition, and Saxon genitive or English possessive.
Eight word classes or parts of speech are commonly distinguished in English: nouns, determinants, pronouns, verbs, adjectives, adverbs, prepositions, and conjuncts. Nouns are the largest word class, and verbs are the second-largest. Unlike many Indo-European languages, English nouns have no grammatical gender.
