Questions & Answers about Kobieta je duże jabłko.
Why didn't the ending of jabłko change since it is the direct object?
Jabłko (apple) is a neuter noun, which we can usually spot by its -o ending. In Polish, neuter nouns are easy when they are direct objects (using the accusative case): they do not change at all. They look exactly the same as their basic dictionary form.
Does the adjective duże (large) also stay in its dictionary form here?
Yes! Because the noun jabłko is neuter and in the accusative case, any adjective attached to it also uses the neuter accusative form. For neuter words, this form is identical to the basic nominative form. So, duże does not change.
The translation says "is eating", but is je also used to mean "eats"?
That's right. Polish does not have a separate continuous tense like English does with "is eating". Kobieta je translates to both "The woman is eating" (happening right now) and "The woman eats" (a general habit).
What is the infinitive (dictionary form) of the verb je?
The infinitive is jeść (to eat). It is an irregular verb, which is why conjugated forms like je (he/she/it eats) and jem (I eat) look quite different and much shorter than the dictionary form.
