I think we may have a problem.Cambridge sagt:
not in use any more, having been replaced by something newer and better or more fashionable:
Gas lamps became obsolete when electric lighting was invented.
obsolet /Adj./ <lat.> veraltet: Sie lassen sich mit bedauerlicher Hartnäckigkeit von gewissen obsoleten ... Grundbegriffen leiten Th. Mann 7,18 (Königl. Hoheit)
Synonyme: alt, ungebräuchlich, veraltet
That's a MESS.
The same confusion exists in English:
1 a : no longer in use or no longer useful <an obsolete word> b : of a kind or style no longer current : OLD-FASHIONED
I dislike the use of "old-fashioned" as a synonym for "obsolete", but both German and English seem to blur to concepts, and it's very frustrating.
How many of you would use "obsolet" and "veraltet" interchangebly? I would prefer a more precise defintion for both obsolete and obsolet.
