Learn Swedish: Förvandlingen blir helt otrolig! - The transformation is turning out absolutely incredible!

The verb blir indicates a change of state, meaning to become or to turn out. Using blir instead of är shows that the transformation is an ongoing process that is turning out to be incredible, rather than just stating a static fact.

Why doesn't the adjective otrolig get a -t ending after blir?

Even though it comes after the verb, otrolig is a predicative adjective describing the subject, förvandlingen. Because förvandling is an en-word (which we can tell from its -en ending), the adjective must agree with it and stays in its basic en-form.

Why is helt spelled with a -t here?

In this sentence, helt is acting as an adverb modifying the adjective otrolig, giving it the meaning of absolutely or completely. When Swedish adjectives are used as adverbs, they take a -t ending, identical to their neuter form.

How does the word förvandlingen break down?

It starts with the verb förvandla (to transform). The suffix -ing turns it into the noun förvandling (transformation), and the final -en makes it the definite form, meaning the transformation.
