Potential (pot) | Event is probable or considered likely | "She probably loves me" |

Admirative (mir) | Event is surprising or amazing (literally or in irony or sarcasm). | "Wow! She loves me!" |

Precative (prec) | Event is requested by the speaker | "Will you pass me the salt?" |
Volitive (vol) | Event is desired, wished or feared by the speaker. | |
Inferential (inferor infr) | Event is nonwitnessed, and not confirmed. | There is no exact English example, although it could be translated as: "She is said to love me" |
