" smaczne" .Well, this adjective is confusing me ! I really can't get what is the ending it takes and in which position in the sentence. It is used in different positions with different endings.
can someone give me a rule for this ?
Well, the adjectives differ according to the grammatical gender of the noun they describe.
-y or -i is the ending for masculine singular, -a for feminine, -e for neuter (and not masculine-personal plural), -i or -y for masculine personal plural. "Jabłko" is neuter, so it's smaczne.
Your first assumption should be that:
if it ends with a consonant, it's probably masculine
if it ends with -a, it's probably feminine
if it ends with -o, -e or -um, it's neuter.
There are exceptions, not even that few of them, but first start with the rule and then learn the exceptions :)
If the noun 'apple' is masculine, why is the form of 'that' neutral instead of masculine as well?
Sounds like people who have previously learned Spanish might struggle with this one, since in Spanish -o typically means masculine.
Patrzysz, patrzysz i stwierdzasz "Tak, tamto jabłko jest smaczne. zjem je sobie". Sens zdań powala. I hope I wrote it well. ;)
