Içtaîl - Içtaîl (the Ithkuil word for 'hypothetical writing system') is a "morpho-phonemic" script whose characters convey both phonetic and morphological (i.e., grammatical) information. Its use is closely tied to the Ithkuil language, whose grammar allows much of the phonological component of words to be morpho-syntactically predictable. Those parts of an Ithkuil word whose pronunciation is predictable are not written, while the characters used to indicate the pronunciation of the unpredictable parts of a word also convey the grammatical information necessary to "reconstruct" the unwritten parts of the word. Words are thus written in a highly abbreviated manner, particularly useful for the highly inflected words of the Ithkuil language. The script is also used alphabetically for transliterating foreign words (as in the Langmaker transliteration below).

Ilaini - The script used in the kingdom of Valdyas. Valdyan scholars recognize no set order for the letters.

Ilaxošaþ - This is the alphabet used to write the Epiq language. It's written from left to right, and is fairly phonemic.
