Proposed Definitions

ba'o

and Fred's axe was starting to get heavier.

co'u

Cessative aspect. It indicates that a situation is at its termination, ending. In the case of a process, it may or may not be completed (cf. 'mo'u').

my face with any kind of cleanser for about six months.

before Garofalo resumes talking to the guest.

Each reader completes the novel in a different way.

pu'o

Prospective aspect. It indicates that a situation is about to take place, not yet realized.

The culture of the indigenous peoples was for a long
time on the verge of being eradicated.

za'o

Superfective aspect. It indicates that a situation is beyond its natural ending point, still taking place.

mi'a ponse le kesma'e noi pa'arcau selcfi i ky traji lo ka malkelci
kei la starflit i lo matra za'o po'urbi'o i lo santa za'o fliba
Here we had this hopeless lemon of a starship - the biggest
piece of shit in Starfleet: engines that kept breaking down,
shields that kept failing.

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.)
