Why is it なさそう and not なそう
"It seems there is none" is なさそう, which escapes the usual rule for 形容詞 (イ-adjectives), which says "drop the い and add そう".
Is there a historical explanation for this exception? And does it have anything to do with なさいません?

Why isn't ある's negative form あらない?
ある is listed in dictionaries as having ラ行五段活用, which would suggest a negative form of あらない. However, that form does not exist. Why not?

Irregularity of あ-series in demonstratives
Why is the あ-series in demonstratives irregular like the following:
ここ そこ あ そこ どこ
(expected あこ)
こう そう あ あ どう

In most hiragana the horizonal stokes are drawn first, but も is an exception. Is there any reason for this?

What are some well known exceptions for 居る (いる) and 有る (ある)?
Today I heard 人形がいる, so I googled around because I thought 居る was only for living things, but I found many examples of this usage. Many for 人形がある as well.
Are there other exceptions for いる/ある?

Are there more irregular verbs like 行く?
I thought when you have a consonant-stem verb ending with -ku you replace it with -ita. For example kaku ("to write") becomes kaita.
But this doesn't happen with iku, which becomes itta, so I guess that makes it irregular – are there any other such…

Can 々 stand for a duplicated kanji with a different reading?
The title may not be so clear, here is what I mean:
々 is used to avoid repeating a kanji. In some cases, the two may not be pronounced the same because the first consonant of the second kanji is voiced (e.g. [時]{とき}[々]{どき}), but they still have the…

Why are 来る and する irregular?
I know that there are more irregular verbs than just this, but their changes are mostly euphonic and not really of any interest to me. What I would like to know is why 来る and する have developed the way they have. I don't want an answer like "It came…

Exceptions to kanji readings
あなた can be written in kanji as 貴方.
However, I noticed that no combination of the readings of those two characters is at all similar to the pronunciation they produce together - this is the first time I've seen this.
How common is it that words…

Similarly, there are verbs with irregular…

On なる and Adverbs
I'm a beginner learner, just learnt about なる and I'm curious about なる vs other verbs when it comes to adverbs.
When using an adverb like 早く on a verb, it modifies the action or manner of the verb. For eg, 早く飲む would mean "drink quickly", or "drink…
