English to Indonesian Art/Literary Linguistics Morphology

Hi
Here's the web page you can find it on:
https://blogs.transparent.com/indonesian/circumfix-ke-an-adj...
It's actually in the title:
"Circumfix “ke-… -an” + Adjectives to form an abstract noun"
Numerous examples of the circumfix in action are given:
baik good; well kebaikan kindness; goodness
cantik beautiful kecantikan beauty
kaya rich kekayaan wealth
sehat healthy kesehatan health
berani courageous keberanian courage
etc.
Many thanks
