What's in English 'I have one pen here?'
'This is a pen.'
That's right! Then 'Is there an apple here?'
'This is an apple.'
Why are they separated by 'a' and 'an'?
that is…
Wow, I was surprised!!
You do not have to be so surprised…
I was also surprised…
I will try to be careful next time.
I will hear again, but why is it divided into 'a' and 'an' even though it is the same singular?
Which do you think is the basic form between 'a' and 'an'?
I am 'a'. Because I do not see nouns that start with vowels quite easily.
I am the same!
How about seeing it in English history?
Why is it only used for singular nouns in the first place?
Originally 'a' and 'an' were the numerals '1'.
I see! That's why the numerals in the meaning of 'one' do not have multiple nouns.
That's right.
Well then, why is 'an' in front of a vowel?
It is said that it is because there is a phenomenon which dislikes vowels and vowels to be pronounced subsequently in English. What is divided into 'an' and 'a' is caused by a phenomenon called 'dropout of n'.
What other examples are there in 'dropout of n'?
'Min (e)' was divided into 'mine' and 'my', but that is one of them!
