There are no adjectives as such in Klingon. Those notions expressed as adjectives in English (such as big, tired) are expressed by verbs in Klingon (be big, be tired). A verb expressing a state or quality can be used immediately following a noun to modify that noun.
The rover -qu' emphatic (section 4.3) may follow verbs functioning adjectivally. In this usage, it is usually translated very.
Dujmey tInqu' very big ships
The rovers -be' not and -Ha' undo, misdo may also follow verbs functioning adjectivally.
puq Doybe' not tired child
HoD QuchHa' an unhappy captain
QuchHa' be unhappy
If a Type 5 noun suffix is used (section 3.3.5), it follows the verb, which, when used to modify the noun in this way, can have no other suffix except the rovers -qu' emphatic, -be' not, and -Ha' undo, misdo. The Type 5 noun suffix follows -qu', -be', or -Ha':
veng tInqu'Daq in the very big city
HoD QuchHa'Daq on the unhappy captain
When a noun has more than one adjective, one of the following forms is used:
SuDbogh Dargh 'ej wovbogh the tea that is green and that is light
Descriptive verbs used adjectivally we have seen take only the suffixes -qu' (tInqu'), -Ha' (ngaDHa') and -be' (lo'laHbe').
