From Bibliotheca Anonoma

Mi is the third syllable in Solresol's alphabet. It can be represented with the written or spoken 'mi', the letter 'm', the color yellow, an arch (in the Solresol stenography), the number 3, the musical note E (in fixed do solfège), or the third note of any major musical scale (in movable do solfège). It is preceded by the note re and followed by the note fa.

The word mi means "Or."

Four-syllable words beginning with mi are generally dedicated to things concerning a person's actions, especially their flaws. Words beginning with mi that are four syllables and contain a repeated syllable are generally employed for isolated adverbs, prepositions, and conjunctions.

The word mimi, sometimes written as MI, indicates that a verb is in the future tense.
