To convert the sentence 'My dictionary is the most expensive of all my books' from the superlative degree to the comparative degree, we need to compare the dictionary with one other group of books, rather than all the books.
In English, adjectives can have different degrees: positive, comparative, and superlative. The comparative degree is used to compare two things.
Here's a step-by-step explanation:
Identify the Superlative Form : In the given sentence, 'most expensive' is the superlative form of the adjective 'expensive.' It indicates that the dictionary is more expensive than all other books.
Change the Superlative to Comparative : The comparative form of 'expensive' is 'more expensive.' When making a comparative sentence, 'than' is typically used for comparison.
Construct the Comparative Sentence : Focus on comparing only two groups. In this case, the dictionary should be compared to another book or group of books. The sentence could be: 'My dictionary is more expensive than any other book I own.'
This sentence effectively uses the comparative degree by comparing just two categories: the dictionary and the other books the student has.
To change 'My dictionary is the most expensive of all my books' to the comparative degree, you should say, 'My dictionary is more expensive than any other book I own.' This comparison highlights that the dictionary is pricier than other books, but not compared to all books altogether. This way, we effectively use the comparative form of the adjective 'expensive.'
