colleague
The German word 'Kollege' is used to refer to a person with whom one works in a professional setting. It is gender-neutral and can be used to describe both male and female colleagues. In German, it is common to use the formal 'Sie' form when addressing a colleague, unless a more informal relationship has been established.
My colleague has a big dog.
This phrase shows a simple declarative sentence. It uses the word 'Kollege' in a possessive context to show that the dog belongs to the colleague.
Can you give that to my colleague?
In this sentence, 'Kollege' is used in the dative case. This is because in German, the indirect object of the sentence (in this case, 'my colleague') usually takes the dative case.
The man over there is a colleague of mine.
This phrase uses 'Kollege' in a slightly more complex structure. The preposition 'von' is used to mean 'of', and the pronoun 'mir' is used to mean 'me' or 'mine'.
