IPA: /əˈnækrəˌnɪzəm/
KK: /əˈnækrəˌnɪzəm/
A person, event, or thing that is placed in the wrong time period, especially something that belongs to an earlier time than the one being discussed.
The use of a typewriter in a modern office is an anachronism.
Anachronism → It is formed from "ana-" (meaning against or back) and "chronos" (meaning time). The word describes something that is placed in a time period where it does not belong, thus being against the correct time.
Think of something that is 'against' ('ana-') the proper 'time' ('chronos') — that's why an anachronism is something out of its correct time period.
