Usage tips
Word structure
The word is made up of the prefix 'un-' (not), the stem of 'glauben' (to believe), and the ending '-lich'. Something that is 'unglaublich' (incredible) is therefore literally 'not to be believed'.
EXAMPLE
Er erzählte uns eine unglaubliche Geschichte von seiner Reise.
He told us an incredible story about his trip.
As an intensifier
Especially in colloquial language, 'unglaublich' (incredible/incredibly) is often used like 'sehr' (very) or 'extrem' (extremely) to intensify another adjective. It then stands directly before that adjective.
EXAMPLE
Die Aussicht vom Berggipfel war unglaublich schön.
The view from the mountaintop was incredibly beautiful.
Positive and negative
In its literal meaning, 'unglaublich' (incredible) can describe something very positive (amazing) as well as something very negative (shocking). The context makes clear what is meant.
EXAMPLE
Sie hat mit unglaublich viel Mut gehandelt.
She acted with incredible courage.

unglaublich vs sehr
very
'sehr' and 'unglaublich' can both make an adjective or adverb stronger. 'sehr' is neutral and almost always fits: 'sehr schön' (very beautiful), 'sehr schnell' (very fast), 'sehr müde' (very tired). 'unglaublich' sounds stronger and often more emotional. You use it when something seems especially large, strong, or surprising. In many everyday sentences, 'unglaublich' can work like 'sehr', but it sounds less calm and a bit more colloquial.
