Clarifying the Use of 'Which' vs. 'What' in Comparative Sentences

When it comes to constructing grammatically correct sentences, understanding the appropriate use of comparatives and superlatives is crucial. This article delves into the proper use of 'which' and 'what' in comparative contexts, providing clear examples and explanations to help improve your sentence structure.

Context and Examples

Consider the following scenario: You have a collection of books and want to express your preference for one of them. Depending on the number of books you are comparing, the choice of words will differ slightly. In the case of three or more books, the correct sentence would be:

'Which is one of my favorite books that I have ever read.'

However, if you are comparing only two books, the sentence changes:

'Which book did you like more.'

This distinction is important because it appropriately conveys the meaning whether you are focusing on a single item or multiple options.

Grammatical Accuracy and Usage

Using past tense in a sentence like 'Which is one of my favorite books that I have ever read' implies a specific context, often referring to a past event or a general preference. Nonetheless, when writing or speaking, consistency in tense is key for clarity. The past tense usage adds a layer of detail that may or may not be necessary, depending on the intent behind the sentence.

Comparative Adjectives

Comparative adjectives are used to compare two items, while superlative adjectives are used to compare more than two. The correct choice of comparative (whether 'more' or 'most') depends on the number of items being compared.

For only two items, the comparative form is used:

'Which book did you like more'

But for three or more items, the superlative form is preferred:

'Which is one of my favorite books that I have ever read'

This distinction can sometimes be confusing, but understanding it helps maintain syntactical accuracy.

Comparative Adverbs

The use of comparative and superlative adverbs follows similar rules. Adverbs are used to modify verbs, adjectives, or other adverbs, and they can also be used to indicate comparison. For example:

'The more she thought about it, the more devastating it became.'

Here, 'the more' indicates a comparative relationship between two states or actions.

Superlative adverbs, on the other hand, indicate the highest degree of comparison:

'Bobby talks the loudest of all the boys'

or

Jill danced the best.

In both these examples, 'the loudest' and 'the best' indicate the highest degree within a group or context.

For further understanding, it is often helpful to consult usage guides or online resources. A reference from the SF State University English Resource Center (link to resource) provides detailed explanations and examples of these forms.

Conclusion

By understanding the appropriate use of 'which' and 'what', along with comparative and superlative adjectives and adverbs, you can improve the clarity and accuracy of your writing. Whether you are describing a book, comparing two items, or expressing a preference, the correct use of these grammatical constructs ensures that your message is clear and effective.
