There are four affixes in this focus category: ag-, -um-, mang- and ma-. Roots will prefer to take only one or some of the prefixes. In some cases the meaning changes from one affix to another, for example, ngisit, "black". If ag- is affixed, agngisit, the meaning is that of there is a likelihood of becoming black or to darken, for example Nagngisitka, "You darkened". However, with -um-, ngumisit, the meaning becomes more of a possibility or conjecture, Ngumisngisitkansa iti tengnat' aldaw, "You might get darker at midday".
