Learn Polish: Znana dziennikarka pisze o sukcesach kobiet w biznesie. - A famous journalist writes about the successes of women in business.

The masculine form is dziennikarz. To form the feminine equivalent, we add the suffix -ka. Notice that the final -z drops out, changing the -arz ending to -arka. This is a very predictable pattern for professions ending in -arz, such as lekarz becoming lekarka or piekarz becoming piekarka.

Why does kobieta become kobiet in this sentence?

kobiet is in the genitive plural case because it expresses possession, translating to 'of women'. For most feminine nouns ending in -a, the genitive plural drops the final vowel entirely, leaving what is called a zero ending.

Both sukcesach and biznesie are in the locative case, but they have different endings. Why?

sukcesach is locative plural because it follows o meaning 'about' (about the successes). The locative plural ending for almost all nouns is -ach. biznesie is locative singular following w (in business). Masculine inanimate nouns usually take -e or -u in the locative singular.
