Usage notes

 * When added onto a stem ending in a consonant, the  applies.
 * When added onto an adjective ending in a suffix such as or, the suffix may or may not be preserved (see examples above for both cases).
 * Negative factitives are not always easily distinguished from positive factitives formed from adjectives beginning with ; compare, derivable either from +  +  or from  +  +  + .

Some examples are more easily derived one way than the other; e.g.  is probably better derived as a positive factitive from.
 * Negative factitives, as well as positive factitives derived from adjectives beginning with or, have some special properties compared with other factitives. They are normally derived specifically with the prefix  and the unstressed suffix , form abstract nouns in unstressed  (when  would normally be expected), and form imperfectives in  (rather than ).
