halochos of aveilus

halochos of shalosh regalim

halochos of yom tov in general

something made new especially for Yom Tov

a prohibition the Gemorah brings to try to understand the machlokes between Beis Hillel and Beis Shamai

the Amorah that refutes Rav Nachman

some thing you cannot use because it did not exist before Yom Tov

a baby that is born on Yom Tov which has extra mazel

yes

no

only if it flowed out by itself

Most fruit: yes; grapes and dates: no

you were planning on shechting the chicken for meat

you can never eat it

you knew the chicken would lay an egg that day

You may eat an egg born on Yom Tov in all situations

correct because rosh hashonoh is one long day

no one holds that view

In Eretz Yisroel, the egg can't be eaten on the second day; in the diaspora it may be eaten

rava did not hold that you could make a conditional eruv tavshilin

saying if this eruv tavshilin is kosher than let me be fulfill my obligation with it, but if it is not kosher than let me rely on the rav of the communities eruv tavshilin

saying if the first day Yom tov is the real day Yom tov then no eruv tavshilin is needed and I can anyways cook on the second day because it is a regular day but if tomorrow is Yom Tov and todays a weekday than let this count as if i made an eruv tavshillin today which would really be Erev Yom tov

No. You might think that the buyer asked for a fertilized egg because they are bigger so the seller might think he could give an unfertilized egg for cheaper the ruling says no the entire sale is canceled

No. We're talking about a case where the buyer was a cheater and he would swap the ratings of the grain. The seller decided to cheat him back rav Ami ruled that was not allowed

there was no such case

Take new dirt and cover it

Cover it and give the animal away

skin it

place its skin in a place where it will be trampled

move it if there is meat attached to it

slaughter it
