Other content words like verbs, adjectives, and adverbs are usually written in a combination of kanji and hiragana, where the root of the word is written in kanji and the inflectional morphemes (the parts of the word that don't change the central meaning of the word's root) are written in hiragana. For example, the native Japanes verb meaning "to swim" is "oyogu" in its plain form, where it is written as 泳ぐ in kanji and hiragana. The kanji 泳 shows the verb's meaning, while ぐ (gu) as in "oyo-gu" shows that the word is in its plain form. The polite form of "to swim" is "oyogimasu", which is written as 泳ぎます in kanji and hiragana. Once again, it has the same kanji, but it ends with different syllables ぎます (gi-ma-su) as in "oyo-gimasu" to show that the word is in the polite form. Native Japanese adjectives usually end in with the syllable い ("-i)," like the word "hayai" (kanji and hiragana: 速い, hiragana only: はやい, meaning: fast), "takai" (kanji and hiragana: 高い, hiragana only: たかい, meaning: tall, high), and "ookii" (kanji and hiragana: 大きい, hiragana only: おおきい, meaning: big or large), while native Japanese adverbs are simply adjectives that end in く ("-ku") rather than い, like "hayaku　"(kanji and hiragana: 速く, hiragana only: はやく, meaning: quickly).
