We (kana)

ゑ, in hiragana or ヱ in katakana, is a nearly obsolete Japanese kana.

katakana origin	恵

It is presumed that ゑ represented [ɰe] (listen) and that ゑ and え indicated different pronunciations until somewhere between the Kamakura period and the Taishō period when they both came to be pronounced as イェ [je] (listen), later shifting to the modern エ [e]. Along with the kana for wi (ゐ in hiragana, ヰ in katakana), this kana was deemed obsolete in Japanese in 1946 and replaced with え and エ. It is now rare in everyday usage; in onomatopoeia or foreign words, the katakana form ウェ (U-[small-e]) is preferred, as in "ウェスト" for "west".

The kana still sees some modern-day usage. Ebisu is usually written "えびす", but sometimes "ゑびす" like Kyōto Ebisu Shrine (京都ゑびす神社, Kyōto Ebisu Jinja),[1] and name of the beer Yebisu (ヱビス), which is actually pronounced "Ebisu". The Japanese title of the Rebuild of Evangelion series is Evangelion: New Theatrical Edition (ヱヴァンゲリヲン新劇場版, Evangerion Shin Gekijōban). Katakana ヱ is sometimes written with a dakuten, ヹ, to represent a /ve/ sound in foreign words; however, most IMEs lack a convenient way to write this and the combination ヴェ is far more common.

Hiragana ゑ is still used in several Okinawan orthographies for the syllable /we/. In the Ryūkyū University system, ゑ is also combined with a small ぃ, ゑぃ/ヱィ, to represent the sound /wi/. Katakana ヱ is used in Ainu for /we/.
