Learn Hardcore Russian: Я позавтракал с другом.

The verb позавтракал is in the past tense and is perfective. It shows that the action of having breakfast was completed. Additionally, its ending (-ал) indicates that the speaker is male; a female speaker would say позавтракала.

What role does the prefix по- play in позавтракал?

The prefix по- is used to form the perfective aspect of the verb. When added to завтракать (to have breakfast), it creates позавтракать, which means to have breakfast in a completed manner. This prefix often signals that the action has been carried out fully or has a defined result.

Why is с другом written the way it is, and what case does it illustrate?

The phrase с другом uses the preposition с meaning with, which always requires the instrumental case in Russian. Here, друг (friend) changes to другом to reflect that it is used in the instrumental case, indicating accompaniment during the action.

Why doesn’t the sentence include a separate word for breakfast as an object?

In Russian, some verbs inherently include their object within their meaning. The verb позавтракать already means to have breakfast, so it’s unnecessary to separately state breakfast. The action is fully expressed by the verb itself.

How would the sentence change if a female speaker were saying it?

If a female speaker were using the sentence, the only change would be in the verb’s ending to match the feminine gender. She would say Я позавтракала с другом instead of Я позавтракал с другом.
