This is the 4993rd most frequent Spanish word.
ende
"Ende" is an archaic Spanish term meaning "hence" or "from there."
In this sentence, 'en adelante' translates to 'from now on,' a usage of 'en' plus 'de,' where 'ende' could have been used historically, meaning 'from here forward'.
De aquí en adelante, no te preocupes por el trabajo.
From now on, don't worry about work.
Here, 'ende' is used as an old form for 'end' or 'completion,' rarely seen in modern language but found in historical contexts.
El ende de su energía se notaba al final del día.
The end of his energy was noticeable at the end of the day.
In this case, 'ende' is used in an archaic way to mean 'therefore,' showing causality. It's not common in modern Spanish.
