IPA: //ˈeɪnʃəntər//
KK: /ˈeɪnʃəntər/
Referring to something that is older or more ancient than another thing.
The ancienter ruins were discovered deeper in the forest than the others.
This word originates from Latin 'antiquus' (meaning old or ancient) combined with the comparative suffix '-er' (meaning more). The word 'ancienter' suggests a comparative form, meaning more ancient or older than something else.
Think of 'ancient' as something very old, and the '-er' indicates a comparison, so 'ancienter' means something that is more ancient.
