When making an Adverb in English, we add -ly onto an adjective. In Thalas'sian, you add -(e)no onto the end of the adjective.
If the adjective is a derived adjective, replace 'el with -eno.
If it ends in a vowel, R, N, or L, suffix -no onto the adjective.
For the rest, suffix -eno.
- af'feran'el (forgetful) --> af'feraneno (forgetfully)
- sinu (good) --> sinuno (well)
- karam (new) --> karameno (newly)
