This is the 4719th most frequent Dutch word.
ergo
"Ergo" in Dutch means "therefore" or "thus."
Here, 'ergo' is used as a conjunction to indicate a logical conclusion or result: "therefore".
Ik ben moe, ergo ik ga slapen.
I am tired, therefore I am going to sleep.
In this sentence, 'ergo' is similarly used as a conjunction to express a cause and effect relationship.
Hij was er niet, ergo we konden niet beginnen.
He was not there, therefore we could not start.
Again, 'ergo' connects the premise about circumstances with the inferred consequence regarding the solution.
