This kana represents the sound 'ku'. It is often used in vocabulary and can function as a grammatical particle to indicate direction or purpose when combined with verbs (e.g., いく → いく, iku, 'to go'). In some cases, it appears in verb conjugations, such as the plain past tense ending (e.g., たべた → たべた, tabeta, 'ate'). For example: 『くに から くる』 (kuni kara kuru, 'to come from a country').
