A person who studies old or outdated things, especially in history or language.
The archaist spent years researching ancient texts to understand the language of the past.
Archaist → It is formed from "archaios" (Greek, meaning ancient) and the suffix "-ist" (meaning one who practices or is concerned with). An archaist is someone who advocates for or uses ancient forms or styles.
Think of someone who is 'concerned with' ('-ist') things that are 'ancient' ('archaios') — that's why an archaist is someone who focuses on ancient styles.
