My understanding is that the adjective comes after the noun, as in this phrase, where "Klingon" is the noun:
tlhingan wochqu' vIlegh (I saw a really tall Klingon)
But in this phrase, where "Klingon" is the adjective and "warriors" the name, the adjective comes before the noun:
nong tlhIngan SuvwI'pu' (Klingon warrriors are passionate)
Could some one please explain?
