To a degree that is hard to believe — the adverb form of staggering, used to turn an adjective all the way up. Its normal position is directly in front of an adjective: staggeringly expensive, staggeringly rich, staggeringly beautiful, staggeringly stupid, staggeringly successful. Think of it as a stronger, more surprised-sounding replacement for 'extremely' or 'incredibly'.

To a degree that is hard to believe到了讓人難以相信的程度 — the adverb form of staggering這是staggering的副詞形式, used to turn an adjective all the way up用來把一個形容詞的程度整個往上推。Its normal position它平常的位置 is directly in front of an adjective是直接放在形容詞前面: staggeringly expensive, staggeringly rich, staggeringly beautiful, staggeringly stupid, staggeringly successfulstaggeringly expensive、staggeringly rich、staggeringly beautiful、staggeringly stupid、staggeringly successful。Think of it as a stronger, more surprised-sounding replacement把它想成是一個更強、聽起來更驚訝的替代詞 for 'extremely' or 'incredibly'給'extremely'或'incredibly'。

Two useful points about how it behaves. It goes with adjectives, not usually with verbs — you say 'staggeringly expensive', not 'it cost staggeringly'. And unlike some strong adverbs, it works with both good and bad qualities; the adjective decides the direction, staggeringly only supplies the size. It also pairs happily with numbers and comparisons: 'staggeringly high', 'staggeringly more than last year'.

Two useful points about how it behaves關於它怎麼用，有兩個實用的重點。It它 goes with adjectives, not usually with verbs是跟形容詞搭配，通常不跟動詞搭配 — you say 'staggeringly expensive', not 'it cost staggeringly'你會說'staggeringly expensive'，不會說'it cost staggeringly'。And unlike some strong adverbs而且跟一些強副詞不一樣, it works with both good and bad qualities它可以跟好的和壞的性質都搭配; the adjective decides the direction方向由形容詞決定, staggeringly only supplies the sizestaggeringly只是提供程度。It它 also pairs happily with numbers and comparisons也很適合跟數字和比較搭配: 'staggeringly high', 'staggeringly more than last year''staggeringly high'、'staggeringly more than last year'。

In register it is a written and educated-speech word — reviews, articles, opinion pieces, and people who read a lot. It is not slangy, but it is not neutral either; it always sounds like the writer is reacting, leaning in, asking you to notice. Because of that, one per paragraph is plenty.

In register在語域上, it is a written and educated-speech word它是書面和受教育者口語的字 — reviews, articles, opinion pieces, and people who read a lot書評、文章、評論性文章、和常常閱讀的人會用。It它 is not slangy不算俚語, but it is not neutral either但也不算中性; it always sounds like the writer is reacting, leaning in, asking you to notice聽起來總像是作者在做出反應、往前傾、要你注意。Because of that正因如此, one per paragraph is plenty一段裡用一次就夠了。

A note: the id above says stagily's neighbour, but the sense line given for this entry is really describing the adjective staggering. The adverb is what you use to modify an adjective; the adjective itself modifies a noun.

A note補充一點: the id above says stagily's neighbour上面的id寫的是stagily的鄰居, but the sense line given for this entry is really describing the adjective staggering但這個詞條給的詞義說明其實描述的是形容詞staggering。The adverb副詞 is what you use to modify an adjective是用來修飾形容詞的; the adjective itself形容詞本身 modifies a noun則是修飾名詞。
