What does superseded mean?
Superseded means that something has been replaced by a newer, more effective, more suitable, or more authoritative alternative. It is used especially for laws, regulations, versions, products, technologies, designs, and ideas that have become outdated or are no longer considered current. The word often implies a formal or orderly replacement rather than an abrupt disappearance: for example, a new edition of a book supersedes the previous edition, while a new system may supersede an older method. Its use in legal, technical, and editorial writing gives it a precise, professional tone, although it is also common in ordinary descriptions of technological change. Superseded things are not necessarily worthless; they may simply have been overtaken by later developments or become unnecessary because their functions have changed.
Made obsolete, outdated, or no longer current by something newer or more authoritative.
"The report has been superseded by a detailed study published this year."
Especially common in legal, technical, editorial, and commercial contexts.
To replace something with a newer, more effective, or more authoritative version.
"The revised standard supersedes the earlier specification."
Usually used in formal or professional writing; the past tense and past participle are “superseded.”
To supersede something is literally to sit above it in authority: the word comes from Latin roots meaning “to sit over” and “to sit upon.”

Where does superseded come from?
The word comes from Latin supersedere, a compound of super- (“over” or “above”) and sedere (“to sit”), originally meaning “to sit above” or “take precedence.” In later English, the verb supersede came to mean “to take the place of” or “replace,” and the past participle superseded developed into a common adjective for something made obsolete by a newer version or successor.
