- 1開創性的、突破性的；典禮／工程則是動土。
Groundbreaking work makes a real new start: new discoveries, new methods, a way nobody used before. Newspapers and universities love the word, and they sometimes stretch it — a slightly new app may be called groundbreaking when it is only new-ish. The picture underneath is building: you break the ground when you first dig to start a house. That literal sense is still alive as a noun: a groundbreaking is the ceremony at the start of construction, with speeches and a shovel. The adjective you meet in class is almost always the praise-word for ideas. Though actually, the tidy dictionary “very new and important” is tidier than real talk, where it can be honest or just advertising.
