2,209. Other Situations That Render a Woman a Zonah
Hilchos Issurei Biah 18:3
A female convert or freed servant, even if she converted or was freed under the age of three, is a halachic zonah because she’s not a born Jew. She is therefore not permitted to marry a kohein. Because of this, if a woman was intimate with a non-Jew, a Gibeonite, a mamzer, a convert from Ammon or Moab, a convert from Egypt or Edom in the first two generations, a man with crushed testes or a severed male organ, or if a chalal was intimate with a Jewish woman, she is ruled a zonah and is prohibited from marrying a kohein. If she was a kohein’s daughter, she is disqualified from eating trumah. The same is true if a yevama is intimate with a man other than her yavam. An ailonis (i.e., a woman who does not mature physically) is permitted to marry a kohein and is not ruled a zonah.
Hilchos Issurei Biah 18:4
If a man is intimate with one of the secondary relations or something similar, such as if he’s intimate with the relative of a woman who performed chalitzah with him or if he was intimate with the woman who performed chalitzah, he doesn’t render her a zonah. The is because she’s not prohibited to him under Biblical law, as was explained in Hilchos Yibum v’Chalitzah.
