office
In German, the word 'Büro' is used to refer to an office, which is a place where people work, especially in a business or professional context. It is a noun and can be used in both formal and informal settings. For example, one might say 'Ich arbeite im Büro' (I work in the office).
I work in the office.
This phrase is used to describe the location of one's workplace, in this case, inside an office. The preposition 'im' is a contraction of 'in dem', which corresponds to 'in the' in English. Thus, 'im Büro' means 'in the office'.
My office is very clean.
This phrase is used to describe the state of someone's office. 'Sehr' is the German word for 'very', and 'sauber' means 'clean'. Using this sentence structure, one can also describe their office using other adjectives.
Where is the office?
This phrase is usually used when one is asking for the location of the office. In this sentence, 'Wo' is 'Where' and 'ist' is 'is'. The phrase structure 'Wo ist [object]?' is a common way to ask for the location of something in German.
