Learn Swedish: Hela ansiktet blev rött av solen. - His whole face went red from the sun.

In Swedish, it is very common to use the definite form of a noun for body parts or clothing when it is obvious who they belong to. The context tells us it is his face, so ansiktet is enough.

Why is the adjective rött written with a -t at the end?

The word for face is an ett-word (ett ansikte). When an adjective describes an ett-word, it takes a -t ending. Notice that the base word röd changes its spelling slightly to rött, giving it a short vowel sound.

Why does "went red" translate to blev rött?

Blev is the past tense of bli (to become). In English, we often use verbs like "went" or "turned" for a change in physical state, but Swedish almost always uses bli for these transformations.

Does the word hela (whole) always force the next word to be definite?

Yes! When you use hela to mean "the whole" or "all of the", the noun that follows must be in its definite form. That is why it is hela ansiktet instead of just "hela ansikte".

Could I use från instead of av for "from the sun"?
