Anachronism

The most appropriate one-word substitution for the given group of words "Someone or something out of time" is "Anachronism."

Here are the explanations of the four options:

1. Anachronism: "Anachronism" refers to something or someone that is out of its proper chronological or historical time period. It describes an element, object, person, or idea that does not fit or belong in the specific time frame being discussed. Anachronisms are often considered incongruous or out of place.

2. Outdated: "Outdated" describes something that is no longer current or relevant due to being surpassed or replaced by newer, more modern versions or ideas. While it suggests being out of time, it does not specifically connote the idea of being out of the proper time period as "anachronism" does.

3. Satire: "Satire" refers to a literary or artistic technique that uses humor, irony, or exaggeration to criticize or ridicule aspects of society, individuals, or institutions. While satire can sometimes highlight anachronistic elements, it is not the specific word to describe something or someone out of time.

4. Codicil: A "codicil" is a legal term that refers to a supplement or addition to a will or testament, modifying or revoking certain provisions. It does not relate to the concept of someone or something being out of time.
