The adjective obsolescent refers to the process of passing out of use or usefulness--becoming obsolete. The adjective obsolete means no longer in use--outmoded in design, style, or construction.
Examples:
- "About the time President Abraham Lincoln issued his initial Emancipation Proclamation in 1862, the New York State Legislature declared the Erie Canal Enlargement Project complete. Then, another major engineering triumph, the New York Central Railroad, consolidated in 1853, was hauling more freight and passengers quicker and cheaper. That brought about the bigger but already obsolescent New York State Barge Canal."
(M.D. Morris, "Erie Canal Exemplifies Engineering," Ithaca Journal, February 17, 2003) - "Adults are just obsolete children and the hell with them."
