"Они написали рассказ, а потом книгу."

Translation: They wrote a short story, and then a book.

[YPSILONZ]

The new voice pronounces потом as "patAm" when in the sentence, and as "pOtam" alone. The correct pronunciation is "patOm".

[RhiannonMcBride]

Yes. It is indeed pronounced па-ТОМ.

[sple00]

Why is "they wrote a story and later a book" wrong. Later is marked read for a reason.

[96Seaturtles]

Is there a difference between потом and тогда? Are they interchangeable?

[servolock]

Is there any reason why it can not be "they wrote the story and then the book" ?

[Lynnda45]

Maybe because it's a short story, not just a story? I'm not sure.

[RhiannonMcBride]

Absolutely none. Рассказ is story.

[NicoraBogdan]

Could it also be correct "и потом" or just "а потом" in this sentence?

[YannOliveira_]

I don't get it, there's is no pattern for perfective and imperfective verbs? do you just have to memorize all of them?
