Jeść takes the accusative case. "Smacznego pomidora" IS the accusative case. The reason for this is that "pomidor" is considered animate (by most people). Basically it's an exception: animate masc. is for animals and some other things such as tomatoes and cigarettes.
I already reported what I believe to be a mistake. Here both smaczny and pomidor are either in the genitive case or in the animate/personal accusative case. It should obviously be the inanimate accusative for things like tomatoes. Treating the tomato as a living thing seems very colloquial at best and should not be featured here. But, that's my opinion.
I'm a little confused as to why the genitive is used here. Wouldn't "Jem smaczny pomidor" be the right way to say this?
Agree - comment above says it's an exception to the rule as tomato is considered animate.
But looking on wiktionary, pomidor is listed as innanimate. So who knows, no moderators have clarified it in this chat.
This is not Genitive, it's an Accusative form of an animate noun, which is identical to Genitive.
English Wiktionary says that Accusative is "pomidor (in colloquial Polish also pomidora)". I'd say that this 'colloquial Polish' is in fact the norm. I have never heard "Jem pomidor" apart from discussions about grammar. Not once in my life.
Most vegetables and fruits are considered grammatically animate without any reason. Some other foods, and some beverages as well. Another group of such nouns are ones connected with technology. With the technology ones, the percentage of people treating them as animate will rather be smaller than those treating food as animate.
Thank you for this explanation. I will picture dancing tomatoes. :-))
