What is Katakana?
Katakana is one of the alphabets used in Japanese writing. We said that every Katakana alphabet has a Hiragana version, and every Hiragana alphabet has a Katakana version. Why do they have two similar alphabets that are even pronouncing or sounding the same but having different characters? The answer to this conundrum lies in the fact that Katakana alphabet is used to spell words that have been borrowed and incorporated in Japanese language from Chinese and Korean languages. One feature that distinguishes Katakana characters from Hiragana characters is that, characters in Katakana are more angular in appearance than Hiragana characters.
Out of the three major systems of writing Japanese, Kana is the most common, and Hiragana and Katakana are two subsystems in this Kana system of writing. Kanji is the most ancient system of writing Japanese while Romaji is the latest to incorporate Roman alphabets to spell Japanese words. Katakana is merely a thousand-year old. That means Hiragana is older than Katakana. This is why there is generous sprinkling of Hiragana characters in Katakana. It is seen that Katakana is used more as a shorthand system.
