Q:

What is the kanji for the word ずれる?

ずれる - 1) slip out of place, get out of position, shift, slide
2)"get out of touch with" or "off" when used of a person
I got curious about what the kanji of the word ずれる is because computers and smartphones don't display any candidates for it. Some google searching made it seem like there isn't one. This seemed absurd to me. How could such a common word not be assigned a character in the course of the hundreds of years that kanji were introduced into Japanese? Unless, it's a new word. But that seems hard to believe too.
So far, the best candidate is 滑. But, only the EDICT2 dictionary mentioned this possibility prefacing the definition with possibly written 滑れる. Unfortunately, looking ずれる and 滑 up in the 研究社新和英大辞典 and 漢字源dictionaries did not confirm anything.
So, is it true that there is no kanji for it? Or is there conclusive evidence that 滑 is in fact the right kanji?

A:

言海, a dictionary published in 1981 1891, says ずれる is a corrupted form of 摩るる【するる】, "to rub; to friction". I think this may explain why ずれる has no kanji. Words formed via sound change (such as ひょっとこ) don't necessarily have kanji.
