Notes

Some of the names of the aspects are changed with respect to CLL, in an attempt to get closer to a more standard terminology:

• inchoative -> prospective (As far as I can tell, other than in Lojban "inchoative" seems to describe {co'a} rather than {pu'o}.)
• continuitive -> progressive ("continuitive" seems to be used for an aspect that emphasizes continuation after a stage of ongoingness, so perhaps closer to {za'o}.)
• cessitive -> cessative (Typo in CLL?)
• achievative -> punctual (I don't know where "achievative" comes from.)
