what does みやしません mean? what is the や or やし doing here? I'm reading a children's book (はれ　ときどき　ぷた) . The boy has asked his mother if she's been reading his diary, and she says no: 「あら、どうして。にっきがどうかしたの？」と、とぼけた。 「いや、べつに。。。」 ぼくは、かあさんのかおをじっくりと、かんさつした。 「みやしませんよ。かあさんのいうことが、しんようできないっていうの？」 The English translation is given as: "Did something happen to your diary?" She pretended not to know what I was talking about. "I wouldn't read your diary, Nori. Don't you even trust your own mother?" I don't understand the phrase みやしません. I know み means "see" or "look," and I know "ません" is negative, but I don't know what the やし is doing. Is it や + しません, and if so, what does the や mean? Thank you! どうもありがとう！
