What is “Circumflex (^)”?

The circumflex (^) is a symbol commonly used in different languages and writing systems, including Japanese. In the context of entering kana characters, the circumflex is used as one of the Japanese input methods. It is a diacritic that can be applied to the kana characters to modify their pronunciation.

In Japanese, the circumflex is used to convert the “っ” sound (small tsu) into a long vowel sound known as a “gemination.” Gemination refers to the lengthening of a sound or extending its duration. When inputting kana characters, the circumflex is placed before the character that is to be geminated.

For example, if you want to type the word “hattari” (はったり) using the kana input method, you would input “h^attari”. In this case, the circumflex indicates that the “tsu” sound in “hattari” should be pronounced with a prolonged duration, resulting in a double “t” sound.

It is important to note that not all kana characters can be used with the circumflex. Only the kana characters “か” (ka), “き” (ki), “く” (ku), “け” (ke), and “こ” (ko) can be geminated using the circumflex input method.

In some Japanese input systems, such as the Romaji input method, the circumflex may also be used to indicate a different function. It can be used to input accented characters, such as “â” or “ê,” which are commonly found in loanwords or foreign names.

To sum up, the circumflex in the context of entering kana characters is a diacritic used to indicate gemination and alter the pronunciation of certain kana characters. It allows for the input of sounds with an extended duration, contributing to the accurate representation of Japanese words and expressions.
