speaking of nedarim- can anyone satisfactorally explain the gemara on pay zatin amud aleph in nedarim which touches on the subject of toch kidday dibbur. the gemara is muchach its not a chazaradike’ din, and the pashtus would be that in some form, the maaseh hasnt yet finished, but kiddushin etc. are different because its a chalois, not stam a maaseh. any thoughts?
