I understand your doubts. For Polish is naturely because robienie means that something is in during. Zrobienie means that something is finished. R.T.

"Zrobienie nawet małego kroku, jest dla dziecka wielkim wyczynem" - here it is a name of the finished activity: Making of even a small step is a great accomplishment for a baby. Are these forms used in Polish? I'm a native Polish speaker and they sound so unnatural to me. It's like using a 19. century language.

Thanks Burzymucha Posłucha. This is exactly the answer I was looking to get and it explains it better than any other answer. Unfortunately, the voting has expired, otherwise I would vote this the best answer because it is. Thanks!!

I feel your pain! It's really difficult to explain because there is no such thing in English. The closest structure that comes to my mind is something like this: "I was singing while taking a shower" (“Śpiewałem, biorąc prysznic”). In this example both activities happen at the same time. You can say: "Śpiewałem, robiąc jajecznicę" (="I was singing while making scrambled eggs"), "Robiąc jajecznicę, rozmawiałem z żoną"("I was making scrambled eggs while talking with my wife"), "Robiąc kanapki, słuchałem radia."("I was making sandwiches while listening to the radio") "Robiąc" is some kind of a verb, NOT a noun. It indicates that something is happened at the same time as the other activity. Just use things like “robiąc” referring to other verbs. If I were you, I would remember these examples and build sentences similar to them. We do the same in phrases like: “I was singing while listening to the radio.” You can learn by heart some phrases: "___________to dla niego czarna magia" "___________to dla niego pestka" "___________to dla niego bułka z masłem" You should replace __________with a noun or verbal noun, such as: "Matematyka to dla niego czarna magia." "Nauka polskiego to dla niego pestka." "Rozwiązywanie zadań to dla niego bułka z masłem."

Hi! About the gerund cause... In the sentence "zrobienie jajecznicy to dla niego czarna magia" you need to use "zrobienie" because we treat it like a noun, not a verb. You could say as well: "zrobienie jajecznicy to JEST dla niego czarna magia". You dont need to use the verb "jest" because it is understandable without it. But what I want to say is that in this sentence you need to use this form because it replace a noun. Like you could say "Narkotyki to dla niego czarna magia" or "Akordeon to dla niego czarna magia". So... normal nouns. But when you want to use the verb in the form of the noun, you can use "robiąc", you need to use the form "zrobienie". With "robiąc" the sentence would sound: "Robiąc jajecznicę, nie ma o niej pojęcia" for example - but... we would never say that, it is completely unnatural. I hope it is more clear for you now.
