The adverb of 'unforgivable': in a way so bad that it cannot be forgiven.

The adverb of 'unforgivable'『unforgivable』的副詞，so bad指糟到that it cannot be forgiven沒辦法被原諒in a way的程度。

In real use it almost always sits in front of an adjective and works as a very heavy 'far too' — 'unforgivably rude', 'unforgivably slow', 'unforgivably late'. The speaker is not calmly reporting; they are angry or being dramatic on purpose.

In real use實際使用時it almost always sits in front of an adjective它幾乎都放在形容詞前面，and works as a very heavy 'far too'當作很強烈的『太過』來用——'unforgivably rude', 'unforgivably slow', 'unforgivably late'像『unforgivably rude』、『unforgivably slow』、『unforgivably late』這樣。The speaker is not calmly reporting說話的人這時候不是在平靜地陳述事實；they are angry而是在生氣，or being dramatic on purpose或故意講得誇張。

That is worth noticing: because the word is so strong, using it about a small thing is a way of showing feeling, and a lot of real examples are exactly that — a restaurant review calling the service unforgivably slow, a friend saying you replied unforgivably late to a message. Nobody is really talking about forgiveness.

That is worth noticing這點值得注意：because the word is so strong因為這個字力道很強，using it about a small thing拿它來說一件小事is a way of showing feeling其實是一種表達情緒的方式，and a lot of real examples are exactly that而且很多實際的例子就是這樣——a restaurant review calling the service unforgivably slow有餐廳評論說服務慢到不可原諒，a friend saying you replied unforgivably late to a message也有朋友說你回訊息慢到不可原諒。Nobody is really talking about forgiveness沒有人真的是在談原諒不原諒的問題。

It can also follow a verb, as in 'he behaved unforgivably', and there it keeps its full serious weight — that one means a genuine wrong, not a joke.

It can also follow a verb它也可以放在動詞後面，as in 'he behaved unforgivably'像『he behaved unforgivably』（他的行為過分到不可原諒）這種說法，and there it keeps its full serious weight這時候它保留完整的嚴肅份量——that one means a genuine wrong這種用法指的是真正的過錯，not a joke不是開玩笑。

Like 'unforgettably', the adjective is far more common than the adverb in everyday speech; the -ly form belongs more to writing, reviews, and people performing their annoyance.
