Learn Finnish: Kerron työkokemuksesta hakemuksessa. - I tell about my work experience in the application.

The verb kertoa (to tell) requires the elative case (-sta or -stä) when you are telling about something. So, työkokemuksesta translates to about work experience.

The translation says my work experience, but there is no word for my in the Finnish sentence. Why?

In Finnish, when the owner of the thing is also the subject of the sentence (the I built into kerron), the possessive suffix is often left out in everyday communication because the context is obvious. In a more formal text, you would add the first-person possessive suffix and write työkokemuksestani.

How does the basic word hakemus (application) become hakemuksessa?

Nouns ending in -us or -ys that are created from verbs (like hakea, to apply) change their stem to end in -ukse- or -ykse- before adding a case ending. Here, the inessive ending -ssa (in) is added to the stem hakemukse-.

Would it be equally correct to say Kerron hakemuksessa työkokemuksesta?

Yes, both word orders are grammatically correct. However, Finnish uses word order for emphasis. The original sentence places hakemuksessa at the end, which slightly emphasizes where you are providing this information.
