1. What does it mean she became nitmeas because she did "sechoch Vyaldus"? Why is sechoch wrong?
2. what is the difference between the terms "meizid" and "bratzon" in general. ( i am not scholar so a simple explanation is fine). Specifically here re if she is metahmeh b meizid is does it not mean she did it bratzon?
1) Sechok means frivolity.
2) As it seems from Yevamos (Perek 6, Mishnah 1), Meizid relates to intent as it relates to the Aveirah: with intent to sin. Its opposite is Shogeg. Ratzon relates to the act itself: with intent to act. Its opposite is Ones.
