I'm marking some definitions as 'archaic' and some as 'obsolete'. From what I understand,
veralten means for something to become outdated.
So I think the definitions could be marked up as:
veraltet- obsolete / no longer in use (past participle)
veraltend- archaic / becoming obsolete (present participle)
Is this correct? Can the words ever be used interchangeably? Are any other words preferred when trying to say that a definition is archaic or obsolete?
