Katakana Letters

The word katakana means "fragmentary kana", as the katakana characters are derived from components or fragments of more complex kanji. With one or two minor exceptions, each syllable (strictly mora) in the Japanese language is represented by one character or kana in each system. Each kana represents either a vowel such as "a" (katakana ア); a consonant followed by a vowel such as "ka" (katakana カ); or "n" (katakana ン), a nasal sonorant which, depending on the context, sounds either like English m, n or ng ([ŋ]) or like the nasal vowels of Portuguese or Galician.
