Spekulation vs Tatsache
fact
'die Tatsache' and 'die Spekulation' are opposites when it comes to evidence. A fact is something that is demonstrably true. Speculation is only an assumption because important information is missing. Learners may confuse the words because both appear in news reports, conversations, or discussions about a topic. But speculation should not be treated like a fact. Use 'Tatsache' for confirmed information, and 'Spekulation' for uncertain assumptions.
Spekulation
Lenas Aussage über den neuen Chef ist nur Spekulation, weil sie ihn noch nicht getroffen hat.
Lena's statement about the new boss is only speculation because she has not met him yet.
Tatsache
Eine wichtige Tatsache ist, dass der Vertrag schon unterschrieben wurde.
One important fact is that the contract has already been signed.
