What kind of language would be categorized as antiquated?

The categorization of language as antiquated pertains specifically to terms and expressions that have fallen out of common use and are no longer relevant in contemporary communication. This is characteristic of obsolete terms that might have been widely used in the past but are now rarely heard or understood by the general population. For instance, phrases or words from Shakespearean times may still hold literary value but are not used in everyday conversation.

Antiquated language typically evokes a sense of history or nostalgia, making it distinct from modern slang or current vernacular that is actively employed in today's discourse. Thus, the focus is on the lack of relevance and usage in present contexts, which makes the correct answer a fitting definition of antiquated language.
