okurigana

are kana suffixes following kanji stems in Japanese written words. They serve two purposes: to inflect adjectives and verbs, and to force a particular kanji to have a specific meaning and be read a certain way. For example, the plain verb form (miru, "see") inflects to past tense (mita, "saw"), where is the kanji stem, and る and た are okurigana, written in hiragana script. With very few exceptions, okurigana are used only with kun'yomi (native Japanese readings), not with on'yomi (Chinese readings), as Chinese morphemes do not inflect in Japanese, and their pronunciation is inferred from context, since many are used as parts of compound words (kango).

The technique in which native scripts are used to inflect adjectives or verbs may have initially taken after Korean scribal strategies, namely gugyeol, and later spread to Japan. When used to inflect an adjective or verb, okurigana can indicate aspect (perfective versus imperfective), affirmative or negative meaning, or grammatical politeness, among many other functions. In modern usage, okurigana are almost invariably written with hiragana; katakana were also commonly used in the past.
