proof
The German word for proof is 'Beweis'. It is used to provide evidence or verification of something. In English, we often use the word 'proof' in the same way, such as when we say 'I have proof that he was there.' In German, 'Beweis' can also be used in this way, such as 'Ich habe den Beweis, dass er da war.' However, it is important to note that 'Beweis' can also refer to a mathematical proof, which is a series of steps used to prove a mathematical statement.
The proof is obvious.
This sentence is used when the proof of something is clearly visible or understandable. It's a very direct statement, expressing that there's no doubt about something because the evidence is clear and undeniable.
They could not provide any proof.
This is used in a context where someone is unable to provide necessary evidence or proof for something. It's often used in legal or formal situations where proof is required for a claim or allegation.
I have sufficient proof for my assertion.
This phrase is used when someone is confident and strong on their stance or claim, as they possess enough evidence or proof to support their position. It is often used in debates or arguments to show conviction.
