Mishnah
The name Mishnah of the collection of Jewish religious law is derived from משנה m-šnh “copy”, since it is supposed to be a written copy of traditional oral law. However, as with all famous ancient texts, the book is likely pun-encrypted, with even the title being a pun. Because the name Mishnah for “copy” is derived from שנה šnh which means both “second” and “disguise”, the name Mishnah can also mean “disguise”.
The word root √šn for “two” & “second” occurs in the forms šnˀ / šny / šnh. Among the derived meanings are “copy” and also “disguise”. You can always add the prefix m- to any word to mean “of X”, so the M-prefixed name Mishnah can also mean “disguise”. For a full discussion of this word root, see number 2.
The Mishnah plus the Gemara commentary is called Talmud, which puns with “deception”.
