very
The word 'sehr' is an adverb in German that is used to express a high degree or intensity of a particular quality or state. It is often translated as 'very' in English and is used in a similar way. For example, 'Das ist sehr gut' means 'That is very good.' It can also be used to emphasize the degree of something, as in 'Ich bin sehr müde,' which means 'I am very tired.' It is important to note that 'sehr' is used before the adjective or adverb it modifies, not after it.
The book is very interesting.
In this example, 'sehr' is used to enhance the adjective 'interessant', making the book not just interesting, but 'very' interesting.
She is a very good friend.
Here, 'sehr' is amplifying 'gute Freundin', emphasizing that she is a 'very good friend', not just a good friend.
