In which terms, if any, is へつ used as an On-reading of the character 閉?


Just now in the chat room we came across a reading of the kanji 閉 that seems
to be either rare or erroneous.

In the [English Wiktionary's entry for
閉](https://en.wiktionary.org/wiki/%E9%96%89#Kanji) there is the following
"Readings section":

  * **On** : へい (hei), へつ (hetsu)
  * **Kun** : とじる (tojiru), しめる (shimeru), とざす (tozasu)

None of us in the chat room at the time could come up with anywhere the へつ is
used?

Is it a correct reading? What is/was it used for?




I found this in a kanji dictionary from 1920s.

<http://kindai.ndl.go.jp/info:ndljp/pid/936724> (set コマ番号 to 866 and you see
the page)

It lists four sounds for 閉, but none of the following 熟語 has a sound other
than ヘイ. I guess this kind of description (ヘツ、ヘチ。方結切。屑。) originally originates
in classical Chinese hanzi dictionaries like 廣韻 or 康煕字典.
