I am bread would be: „Jam (jest) chleb” or „Jam chleb (jest)” grammar itself (but not this course) allows to split ending from verb, leaving it as if it was 3rd person and attaching this suffix to any of the words in a sentence.
Is chleb accusative or nominitive in this instance? Are those proper case names?
In this case, it's accusative. Chleb remais the same either in nominative and in accusative.
You can take as a rule that masculine nonanimate singular nouns have the accusative=nominative, and masculine animate singular accusative=genitive
Why doesn't the basics section show the verb in its irregular form? Otherwise beginner speakers will have no clue.
GAH I wrote I et bread and got it WRONG! grr.... 20 point streak for this...
