The metachronism-prochronism contrast is nearly [[Synonym|synonymous]] with parachronism-anachronism, and involves postdating-predating respectively.<ref name=":0">{{cite journal |last1=Landwehr |first1=Achim |last2=Winnerling |first2=Tobias |date=2019-10-02 |title=Chronisms: on the past and future of the relation of times |url=https://www.tandfonline.com/doi/full/10.1080/13642529.2019.1677294 |journal=Rethinking History |language=en |volume=23 |issue=4 |pages=435–455 |doi=10.1080/13642529.2019.1677294 |issn=1364-2529}}</ref>{{Rp|page=3}}

===Parachronism <!-- 'Parachronism' redirects here-->===
A '''parachronism'''<!--boldface per WP:R#PLA--> (from the [[ancient Greek|Greek]] {{lang|grc|παρά}}, "on the side", and {{lang|grc|χρόνος}}, "time")<ref>{{cite web |title=parachronism {{!}} Etymology of parachronism by etymonline |url=https://www.etymonline.com/word/parachronism |access-date=2024-09-12 |website=etymonline.com |language=en}}</ref> postdates.<ref name=":0"/>{{Rp|page=9}} It is anything that appears in a time period in which it is not normally found (though not sufficiently out of place as to be impossible).

This may be an object, idiomatic expression, technology, philosophical idea, musical style, material, custom, or anything else so closely bound to a particular time period as to seem strange when encountered in a later era.  They may be objects or ideas that were once common but are now considered rare or inappropriate.  They can take the form of obsolete technology or outdated fashion or idioms.<ref>{{Cite web |title=Parachronism, n. meanings, etymology, and more |url=https://www.oed.com/dictionary/parachronism_n?tab=meaning_and_use#31846971 |url-access=subscription |access-date=28 February 2025 |website=Oxford English Dictionary}}</ref>

===Prochronism <!-- 'Prochronism' redirects here-->===
A '''prochronism'''<!--boldface per WP:R#PLA--> (from the [[ancient Greek|Greek]] {{lang|grc|πρό}}, "before", and {{lang|grc|χρόνος}}, "time")<ref>{{cite web |title=Definition of PROCHRONISM |url=https://www.merriam-webster.com/dictionary/prochronism |access-date=2024-09-12 |website=merriam-webster.com |language=en}}</ref> predates.<ref name=":0"/>{{Rp|page=7}} It is an impossible anachronism which occurs when an object or idea has not yet been invented when the situation takes place, and therefore could not have possibly existed at the time. A prochronism may be an object not yet developed, a verbal expression that had not yet been coined, a philosophy not yet formulated, a breed of animal not yet evolved or bred, or use of a technology that had not yet been created.<ref>{{Cite web |date= |title=Prochronism, n. meanings, etymology, and more |url=https://www.oed.com/dictionary/prochronism_n?tab=meaning_and_use |url-access=subscription |access-date=28 February 2025 |website=Oxford English Dictionary}}</ref>
===Metachronism===
A '''metachronism''' (from the [[ancient Greek|Greek]] {{lang|grc|μετά}}, "after", and {{lang|grc|χρόνος}}, "time")<ref>{{cite web |title=Metachronism |url=https://www.merriam-webster.com/dictionary/metachronism |access-date=26 January 2024 |website=[[Merriam-Webster]]}}</ref> postdates.<ref name=":0"/>{{Rp|page=7}} It is the use of older cultural artifacts in modern settings which may seem inappropriate. For example, it could be considered metachronistic for a modern-day person to be depicted wearing a [[top hat]] or writing with a [[quill]].<ref>{{Cite web |title=Metachronism, n. meanings, etymology and more |url=https://www.oed.com/dictionary/metachronism_n?tab=meaning_and_use#37032543 |url-access=subscription |access-date=28 February 2025 |website=Oxford English Dictionary}}</ref>
