一段動詞が五段動詞に進化できますか？


日本語の文法では五段動詞の方が一段動詞より多いです。文法が変化すると、一段動詞が五段動詞に変化する可能性がありますか？

私は日本語を練習したいです。上手くなければすみません。




A few evidences may show people are inclined to use godan verbs more often.

ら抜き言葉 refers to making a "wrong" potential form from ichidan verbs as if they
were godan verbs.

  * [食べられる (taberareru) vs 食べれる (tabereru)？ The phenomenon of ら抜き (ra-nuki) in Japanese](http://selftaughtjapanese.com/2015/02/27/%E9%A3%9F%E3%81%B9%E3%82%89%E3%82%8C%E3%82%8B-taberareru-vs-%E9%A3%9F%E3%81%B9%E3%82%8C%E3%82%8B-tabereru%EF%BC%9F-the-phenomenon-of-%E3%82%89%E6%8A%9C%E3%81%8D-ra-nuki-in-japanese/)

Recent verbs coined from loanwords or onomatopoeia are usually godan verbs.

  * [How do Japanese people infer if a verb is a ichidan verb or a godan ending in ru?](https://japanese.stackexchange.com/q/43214/5010)

In addition, some people on the net like to jokingly use the wrong imperative
form for ichidan verbs as if they were godan verbs. On sites like 2ch you may
find people saying よく見れ or やめれ instead of よく見ろ or やめろ. (Note that these are
still jokes like "All your base are belong to us.")

These may indicate ichidan verbs may become unpopular _far_ in the future.
Still, I'm not aware of any ichidan verb that was turned into godan
completely. Except for the ら抜き, the conjugation rule for ichidan verbs are
well preserved, and no one say 見らない or 食べります, for example.

**EDIT:** According to [this
entry](http://kobun.weblio.jp/content/%E8%B9%B4%E3%82%8B), 蹴る was an ichidan
verb in archaic Japanese, but somehow merged into the godan verb family in
modern Japanese. [Many people are still confused with the imperative form of
蹴る](https://detail.chiebukuro.yahoo.co.jp/qa/question_detail/q1139286106).
Nevertheless, such a conversion seems to be very rare in the history.
