Shikoku dialect

The Shikoku dialects are a group of the Japanese dialects spoken on Shikoku.
The Shikoku dialects are:

The Shikoku dialect has many similarities to the Chūgoku dialect group in grammar. Shikoku dialect uses ken for "because", and -yoru in progressive aspect and -toru or -choru in the perfect. Some people in Kōchi Prefecture use kin, kini, or ki instead of ken, -yō or -yū instead of -yoru, and -chō or -chū instead of -choru.
The largest difference between Shikoku dialect and Chūgoku dialect is in pitch accent. Except southwestern Ehime and western Kochi, many dialects in Shikoku use the Kyoto-Osaka-type accent or its variations, and are similar to Kansai dialect, but Chūgoku dialect uses a Tokyo-type accent.
The differences between zi and di and between zu and du, which have been lost in standard Japanese, have been preserved in the southern part of the Shikoku dialect region.
