This suffix indicates that what the noun refers to is bigger, more important, or more powerful than it would be without the suffix.
SuS wind, breeze SuS'a' strong wind
Qagh mistake Qagh'a' major blunder
woQ power woQ'a' ultimate power
This is the opposite of the augmentative suffix. It indicates that what the noun refers to is smaller, less important, or less powerful than it would be without the suffix.
SuS wind, breeze SuSHom wisp of air
roj peace rojHom truce, temporary peace
This is an infrequently used, but nonetheless very interesting noun suffix. It is a very peculiar suffix because it is the only suffix that begins with a vowel rather than a consonant. (Though there are no examples, it is suspected that for those few nouns which end in a vowel, ' is inserted before this suffix.) The suffix usually follows a noun referring to a relative (mother, father, etc.), but it could also follow a noun for an animal, especially a pet, and means that the speaker is particularly fond of whatever the noun refers to. It is strongly suggested that non-native speakers of Klingon avoid this suffix unless they know what they are getting into.
