Questions & Answers about Træet vokser og bliver stort.
Why does the adjective stor have a -t at the end here?
Adjectives in Danish must agree with the noun they describe, even when they come after the verb. Because træet is a neuter noun (et træ), the adjective takes the neuter -t ending, making it stort.
I thought bliver meant 'to stay' or was used for the future tense. Why does it mean 'becomes' here?
The verb at blive is very versatile. Its primary meaning is a change of state ('to become' or 'to get', as in 'gets big'). While it can also mean 'to stay' or be used to talk about the future, here the tree is changing size, so 'becomes' is the literal and correct meaning.
Since the tree is growing upward, shouldn't it be vokser op?
No, you only use vokser op ('grows up') when talking about a person or animal's childhood and upbringing. For plants, hair, or general physical size, you just use the single verb vokser.
