- 1危險地；岌岌可危地（常跟 close 連用，表示「再差一點就不妙」）
Perilously means “in a dangerous way,” and it often adds an extra feeling: something bad is close, even if it has not happened yet. If a glass is perilously close to the edge, it has not fallen — but it very easily could. Writers like “perilously close,” “perilously thin,” “perilously close to failing,” because those phrases paint the moment just before trouble. It is a little formal. In casual talk people more often say “,” “way too close,” or “almost.” Though actually, perilously is not only about accidents; people also use it when a result is hanging by a thread, like a team perilously close to dropping out.
組成perilous + -ly（變成副詞）。來自中古英語 perilously。
