Etymology: "Superannuated" was first put to use in English in the 1600s,
having been borrowed from Medieval Latin "superannuatus," past participle
of "superannuari" ("to be too old") -- from Latin "super-" ("over" or
"above") and "annus" ("year"). Shortly thereafter, we made our own verb,
"superannuate," from the adjective. "Superannuate" meant "to pension off"
as well as "to declare obsolete," meanings that are still in active use.

Date: 1740

: incapacitated or disqualified for active duty by advanced age

"Superannuated" can be a good word for referring to something (or someone)
that has outlived its usefulness (such as "a drawerful of superannuated
neckties").
