3M - Misspelled, Mistranslated or Mispronounced?
Those learning Gemoro, especially Daf Yomi who for the past year have been learning the three בבות in Nezikin are familiar with the words זבין (with a Yud) and זבן (without the Yud). זבין means sold and זבן means bought.
Therefore חד גדיא דזבין אבא should be translated, my father sold, or change the spelling to דזבן.
Mori V'Rabi Harav Hagaon R. Shlomo Miller Shlita said, there is a third possibility to keep the spelling with a Yud but change the pronunciation to DEZVIN instead of DEZABIN.
The translation will change to " One kid the "purchase" of my father.
