You can think of it as sadness attached to something else in the sentence. In its most concrete use, the sadness sits on a person's behaviour — you hear it in the voice, see it on the face. From there it drifts off the person and onto the whole statement: the speaker steps in to say 'this news is bad, and I'm sorry about it'. In a small set of phrases it drifts one step further and simply makes a bad thing sound worse.

可以想成「難過」黏在句子裡的某個東西上。最具體的用法裡，它黏在一個人的舉動上——聲音、表情、動作看得出他在難過。再來它離開那個人，黏到整句話上：說話的人跳出來說「這件事情不好，我也覺得可惜」，這時句子裡的人根本不必難過。最後在少數幾個固定搭配裡，它只剩下把壞事講得更重的力氣。三種用法看起來差很遠，但都是同一份難過往外擴散。原始詞典資料5 筆記錄
