Many masculine nouns add a -i or -u to the stem when creating the singular definite form.
a student = një student
the student = studenti
The -i form is more often used, but if the stem ends in a k, g, h or a stressed i or e, then the -u form is used. Keep this rule in mind, but also remember that many nouns are irregular. The complete set of rules for creating the definite form are complicated and will be covered in their entirety in later lessons.

Many feminine nouns use a -a or -ja appended to the stem to create the singular definite form.
a (female) friend = një shoqe
the (female) friend = shoqja
If the indefinite form ends in a -ë, then the -a ending is often used. If the indefinite form ends in a -e then the ending -ja is often used. Again, many feminine nouns are irregular, in later lessons, more rules will help sort out the complicated mess.

Plural forms of the regular indefinite, for both masculine and feminine nouns, are formed by appending a -ë or -e to the noun stem.

The plural forms of the regular definite, for both masculine and feminine nouns, are formed by appending a -t or sometimes a të to the indefinite plural form.
