Why is も used instead of が in the sentence 「日本ではクモを見ると良いことがあると言う人もいますよ」


What is the exact sentiment expressed by も in this sentence as opposed to が?

日本ではクモを見ると良いことがあると言う人もいますよ

It's a sentence in response to someone saying "I saw a spider in my room, I
was scared".




も is used instead of が to add the meaning of "even" or "also." See for
comparison the following examples:

> 日本ではクモを見ると良いことがあると言う人がいますよ
>
> In Japan, there are people who say that seeing a spider is a good thing.
>
> 日本ではクモを見ると良いことがあると言う人もいますよ
>
> In Japan, there are also people who say that seeing a spider is a good
> thing.

Depending on context, one can also translate も as "even," as Istraci does:

> In Japan, there are even people who say that seeing a spider is a good
> thing.

So も introduces an element of comparison, implying that there are people who
think that seeing a spider may be a good thing, as well as those who think
that it is a bad thing. In natural colloquial English, perhaps one could drop
the "even" or "also," as these seem somewhat stilted in the context of a
conversation, and introduce a word like "well" instead:

> 部屋でクモを見て、怖かった！
>
> 日本ではクモを見ると良いことがあると言う人もいますよ。
>
> I got scared because I saw a spider in my room!
>
> Well, in Japan there are people who say that seeing a spider is a good
> thing.
