Understanding One-Word Substitution for "A Thing No Longer in Use"

This question asks for a single word that accurately replaces the phrase "A thing no longer in use." This is a common type of vocabulary question known as one-word substitution.

Let's look at the given options and determine which one best fits the meaning of something that is no longer in use.

Analyzing the Options for "A Thing No Longer in Use"

• Absolute: This word means complete, total, or without limitations. For example, "absolute power" or "an absolute truth." It does not mean something is no longer in use.
• Broken: This word means separated into pieces or parts by force, or made inoperative. A broken item might not be in use, but the reason is damage, not necessarily that it has simply gone out of use over time or due to obsolescence.
• Damaged: This word means harmed or injured, reducing value or usefulness. Similar to 'broken,' a damaged item might not be in use, but the primary meaning relates to physical harm rather than simply being superseded or no longer popular or practical.
• Obsolete: This word means no longer produced or used; out of date. This definition perfectly matches the phrase "A thing no longer in use." Items become obsolete when they are replaced by newer versions, when the technology is outdated, or when they are simply not needed or popular anymore.

Identifying the Correct One-Word Substitute

Based on the analysis of the options, the word that means "A thing no longer in use" is 'Obsolete'. An obsolete item is something that is no longer current or functional in its original context because it has been replaced or has become outdated.
