Final answer:
The word 'outdated' means something is no longer in use or has fallen out of fashion or relevance. This applies to objects, technology, and even language as society and technology advance, making previous terms or items outdated.
Step-by-step explanation:
The meaning of the word 'outdated' is 'No longer in use'. Something that is outdated has fallen out of fashion, use, or relevance. It is behind current trends, technology, or thinking. An example of this would be textbooks in a classroom that contain information that is no longer current and have been replaced by more recent editions; such textbooks are considered outdated. Another instance could be methods or devices that were once popular or widely used but have now been superseded by newer innovations, like an Oldsmobile car that is considered outdated in comparison to modern vehicles. The evolution of language reflects changes in technology and society. For instance, just two decades ago, words like 'e-mail,' 'Internet,' and 'downloading' would have been unknown to most people, but now they are a fundamental part of our vocabulary, whereas words describing older technology might become outdated.
