Q. How do you spell the name of the month in the ketuvah, Cheshvan or Marcheshvan? Is Marcheshvan written as one word or two?

A. The correct name for this month is the one word Marcheshvan (Beis Shmuel – Even Ha’ezer 126: 21, Aruch Hashulchan ibid. 17 Nachlas Shiva 4). If he only wrote Cheshvan, after the fact it is acceptable (Get Pashut ibid,)
