IPA: /ˈeɪnʃəntɪst/
KK: /ˈeɪnʃəntɪst/
The term refers to something that is the oldest in age or existence, often used to describe civilizations, artifacts, or historical periods.
The ancientest ruins in the city attract many tourists each year.
Ancientest is formed from "ancient" (from Latin "antiquus", meaning old or former) and the superlative suffix "-est" (meaning most). The word "ancientest" refers to the most ancient or the oldest in time.
Think of 'ancient' meaning very old, and when you add '-est', it indicates the most of that quality — so ancientest means the most ancient.
