Frances Karttunen: 

CACTIMAN(I) for there to be silence, stillness, absence of activity; for the weather to be fair / casa desamparada que no se habita, o hacer bonanza y buen tiempo, o haber silencio un poco de tiempo, o estar la ciudad asolada de repente y destruída (M) The initial element of this construction is restricted in occurrence . M has it in cactiuetzi ‘to fall quiet,’ and T has CACTI ‘to moderate.’ See CACTI, MAN(I).

Lockhart’s Nahuatl as Written: 

Probably related to an old intransitive form of cahua, plus -ti-, mani. The root cac- is found only in constructions with auxiliary verbs. A form that looks like cacti in the Tetelcingo dictionary is the equivalent of cactiuh. Cactimani is not attested in any other tense than the present, but presumably it would be the same as any other -timani auxiliary.
