我想用一个英文单词来解释会清楚些 “fear” for verb means 害怕 He fear the enemy will kill him. 他害怕敌人会杀了他。 “fear” for noun means 恐惧 Fear caused his hair to rise. 恐惧使他的毛发竖立起来。 如果还有问题可以add me

害怕 and 恐惧 both mean "fear" with little difference. 害怕 is generally used as a verb, which you can hear on daily-life basis. 恐惧 is more of a literary word, and is normally used as a noun. Of course, you can use "恐惧" as a verb, depending on our context.

害怕是即将发生,恐惧是担心有什么发生

Fear is about to happen, fear is to worry about what happens

恐惧 this chinese word is more formal than 害怕
