True.
Some words early in their history signified something quite low or humble, but changed as time went by to designate something agreeable or pleasant. Take a common term "nice" for example. Its original meaning was "ignorant", then changed to "foolish" and now elevated to mean "delightful, pleasant". （More examples: Marshal and constable meant a "keeper of horses', but now have risen to a "high ranking army officer" and "policeman" respectively.）
正确。
在它们的历史早期，有些词表示一些相当卑微或低下的事物，但随着时间的推移而改变，用以表示一些令人愉快或舒适的事物。以一个常见的词语“美好的”为例。它最初的意思是“无知”，后来改为“愚蠢”，现在发展为“愉快的，舒适的”。（更多的例子：Marshal（警察局长）和constable（警察）都是的意思是“马夫”，但现在已经分别上升到“高级军官”和“警察”的意思了。
