Predicate adjectives that begin with "a"

Today, I learned an adjective that begin with "a" is a predicative adjective almost all cases.

In the other words, this adjective don't modify nouns, but is used for a complement.

For example, afraid, alike, alone, asleep, alive awake, etc.

(Of course, there are exceptions such as unable, well, glad, worth, pleased, liable.)

I became curious, so I searched for them.

In Old English, these adjectives had a meaning of progressive, or was a past participle, so they often represent a state.

Also, a progressive form in Old English was represented like "bēon + on + V-ing."

Through Medium English from Old English, prefixes "an-" and "a-" came to be used instead of "on."

It is said that "alive" or "asleep" is exist as a vestige of that.

This is the reason why an adjective that begin with "a" is a predicative adjective.

Also, a present participle was represented like "bēon + V-ende" in Old English, and this became "be + V-ing," and finally, a progressive form "be + V-ing" was born by combining a gerund and a present participle.

Ah, I think my sentences are so hard to understand. I'm sorry.

私は、a で始まる形容詞はほとんど全て叙述用法でのみ使われると学びました。

言い換えれば、名詞を修飾せず、補語としてのみ使用される形容詞です。

例えば afraid, alike, alone, asleep, alive, awake などです。

（unable, well, glad, worth, pleased, liable などの例外もあります。）

少し気になったので、少し詳しく調べてみました。

これらの形容詞は古英語において、進行形の意味を持っていたり、過去分詞であったりしたため、状態を表すことが多いようです。

また、古英語の進行形は、bēon + on + V-ing のように、動名詞の前に on をつけて表していました。

古英語から中英語にかけて on の代わりに接頭辞 an- そして a- が使われるようになり、その名残として alive や asleep があると言われています。

これが、a で始まる形容詞が叙述用法で使われる理由です。

また、古英語で現在分詞は bēon + V-ende というように表されており、これが be + V-ing となり、動名詞と現在分詞が組み合わさって現在の進行形が生まれました。

あぁ、理論がめちゃくちゃでわかりにくいかもしれません。ごめんなさい。

  'these adjectives' is plural so 'was' -> 'were' :) I thought that you were talking about the 'progressive form' so I changed it to that -if I'm wrong, sorry;;

  I had to look up what 'Middle English' was haha -didn't even know it was a real thing! www

This was a tough post to correct! Your English was very good -don't worry! :) It's just that the grammatical terms and the topic in general isn't something native speakers come across on a daily basis! I learnt a lot today~ Thank you :)

• For example, afraid, alike, alone, asleep, alive awake, etc.
• For example: afraid, alike, alone, asleep, alive awake, etc.

  I think a semi colon is appropriate here.

  I'm pretty sure you can use it here too.

  You don't have to say "online." But if you want to be more specific, you can put it here.

• In Old English, these adjectives had a meaning of progressive, or was a past participle, so they often represent a state.
• In Old English, these adjectives were used in the progressive tense, or were used as past participles, so they often represent a state.

  "Progressive" also can mean "to make progress." When speaking about grammar terms, I think it is a good idea to say "the progressive tense." Although it is not required to say "tense," it does help keep things clear.

• Also, a progressive form in Old English was represented like "bēon + on + V-ing."
• Also, a progressive form in Old English was represented constructed like this: "bēon + on + V-ing."

  I think that "constructed" is a good word to use here. We often talk about sentence constructions in English, so it makes sense to use it. Your example of "bēon + on + V-ing" is an example of a sentence construction.
  
  I think it is good to add the word "this." "Bēon + on + V-ing" is only one example. There are many other examples that could be used. In fact, it might even be a good idea to describe the construction first, and then give your example. For example:
  
  "In English a progressive form is constructed by adding the suffix "-ing" to the end of a verb. For example: run + ing."
  
  Two sentences written like this are very clear.

• Through Medium English from Old English, prefixes "an-" and "a-" came to be used instead of "on."
• Through Middle English from Old English, prefixes "an-" and "a-" came to be used instead of "on."

  "Middle" seems to be used to describe times or distances.
  "Medium" seems to be used to describe cooking (the egg was medium done) or thickness (the thank had medium armor).
  
  I say "seems to be used" because I just thought about it by myself for a little bit before posting.

• Also, a present participle was represented like "bēon + V-ende" in Old English, and this became "be + V-ing," and finally, a progressive form "be + V-ing" was born by combining a gerund and a present participle.

  Some people might not realize that "V" stands for verb. If you want, you could say something like
  
  "Also, a present participle was represented like "bēon + V-ende" (where "V" represents a verb) in Old English..."

I think that this is a very difficult subject for you to write about! I am impressed. Writing about the grammar of a language that you are learning is not easy. It is even more difficult to write about the history of that grammar. You are very brave!
