- Use "-en" as a suffix when the noun ends with a consonant to emphasize interconnectedness with oneself or the collective.

- Use "-nen" as a suffix when the noun ends with a vowel or a vowel sound to emphasize interconnectedness with oneself or the collective.

-If a noun ends with a consonant sound but is written with a vowel (ex: “house”), simply add -n to emphasize interconnectedness with oneself or the collective.

If a noun ends with a double vowel (ex: “tree”), a hyphen is added between the last vowel and “-en” (ex: “tree-en”).

Here are examples illustrating the use of suffixes "-en" and "-nen" in Presensia:

1. Su si frienden yün si familynen. (The friends are one with the family.)
2. Su si pe si riveren si clearnessen si wateren. (This river has clear water.)
3. Su si pe si housen si whiteness si wallen. (This house has white walls.)
4. Su si mountainen yün si valleynen. (The mountains are one with the valleys.)
5. Su si winden si strengthen si breezen. (The wind is one with the strong breeze.)
6. Su si oceanen si deepnessen si bluenen. (The ocean is one with the deep blue.)
7. Su si caten yün si dogen. (The cat is one with the dog.)
8. Su si pe si woodsen si fullnessen si  lifen. (This forest is full of life.)

These examples demonstrate the use of suffixes "-en" and "-nen" to emphasize interconnectedness with oneself or the collective in Presensia. They also show the use of "-n" for words like "house" that end with a consonant sound but are written with a vowel.
