Questions & Answers about Журналист пишет статью о городе.
Russian simply has no articles.
Words like журналист and статью can mean “a journalist / the journalist” and “an article / the article” depending only on context.
So Журналист пишет статью can be understood as:
- “A journalist is writing an article”
- “The journalist is writing an article”
Both are possible; Russian does not mark this difference in the sentence itself.
Пишет is:
- 3rd person singular (he/she/it)
- present tense
- imperfective aspect
- from the verb писать (to write)
In English it can mean both “writes” (habitual action) and “is writing” (action in progress).
Russian does not distinguish these two with different forms; context decides which English translation is better.
