Breakdown of Ich bitte meinen Bruder um Hilfe.
Questions & Answers about Ich bitte meinen Bruder um Hilfe.
Because Bruder is the direct object of bitten, and bitten takes the accusative case for the person you ask.
- der Bruder = nominative
- meinen Bruder = accusative
So:
- Ich bitte meinen Bruder ... = I ask my brother ...
This change only shows clearly on masculine nouns. If it were a feminine noun, the article might look the same in nominative and accusative.
It is accusative singular masculine.
You can see that from:
- mein Bruder = nominative
- meinen Bruder = accusative
This is a very common pattern in German: masculine words often change in the accusative, while neuter and feminine often do not change as much.
Because the verb pattern is:
jemanden um etwas bitten = to ask someone for something
So the sentence is built like this:
- Ich = subject
- bitte = verb
- meinen Bruder = the person I am asking
- um Hilfe = the thing I am asking for
So um is not random here. It belongs to the expression jemanden um etwas bitten.
