Use "adjectival" in a sentence
"Gonzales apparently thought no one would read beyond the overly clever, first-word adjectival euphemism in the memo's title: Humane Treatment of al-Qaeda and Taliban Detainees."
"To do that, you need either these intensifiers (hen3, zhen1 etc.) or a so-called adjectival verb (don't worry ...) like gao1 (tall) gui4 (expensive) or xiao3 (small)."
"Intransitive verbs may similarly be formed from "adjectival" roots, and indicate the acquiring of the characteristic or quality expressed in the root: lacigxi, to become tired, to get tired. varmigxi, to become warm, to get warm. maljunigxi, to become old, to age."
