incredible
So extreme, great, or extraordinary that one can hardly believe it or grasp it mentally; unbelievable.
Die Zerstörung durch den Sturm war einfach unfassbar.
The destruction caused by the storm was simply incredible.
The word is easy to understand if you break it down: the prefix 'un-' means 'not', the stem 'fass-' comes from 'fassen' (here in the sense of 'begreifen'—to grasp or understand), and the ending '-bar' means '-able' or '-ible'. So 'unfassbar' (incredible) literally means 'not able to be grasped'.
Seine Dummheit ist für mich einfach unfassbar.
His stupidity is simply incredible to me.
'Unfassbar' (incredible) is very often used as an adverb to intensify another adjective or a verb extremely. It then means something like 'unglaublich' (unbelievably) or 'extrem' (extremely).
Das Konzert gestern war unfassbar gut.
The concert yesterday was unbelievably good.
This word always expresses a strong emotion, for example shock, amazement, anger, or great joy. It is used for situations that are far outside the norm.

'unglaublich' and 'unfassbar' are very close in meaning. You use both when something is so extreme or special that you can hardly believe it. 'unfassbar' emphasizes more strongly that you can hardly grasp something internally or mentally. It often fits very strong feelings, whether positive or negative. 'unglaublich' is a bit more general and can also simply express a strong judgment.
