Understanding the Basics of 'What' and 'Which'

The Semantic Rule of 'What' and 'Which'

The question words 'what' and 'which' play an essential role in English grammar. From a semantic perspective, 'what' is often used when the range of possible answers is open-ended, or when the speaker is unaware of the potential options. On the other hand, 'which' is used when the speaker wants the listener to choose from a limited, definite set of options. A better understanding of these semantic rules can help in accurately using 'what' and 'which' in sentences and thereby enhancing communication skills.

'What' and 'Which' in Interrogative Sentences

Interrogative sentences are a common area where 'what' and 'which' find crucial application. In this case, 'what' is used in general questions, while 'which' is used when the speaker believes that the listener knows the specific choices available. For instance, in a question such as 'Which car do you want to buy from the ones we saw at the dealership?', the use of 'which' implies that the speaker is asking the listener to choose from a clear set of options, specifically, the cars that were seen at the dealership. Understanding this element can increase proficiency in inquiry and comprehension skills.

Exactness of Answers with 'What' and 'Which'

'What' and 'which', despite their similarities, can prompt different levels of specificity in responses. While 'what' questions usually garner general answers, 'which' questions elicit more precise responses due to their nature of providing a limited set of options. This distinction becomes clearer in situations where both 'what' and 'which' questions are applicable, yet yield varying degrees of exactness in answers.

'What' and 'Which' in Context

'What' and 'Which' in Conversational English

In the context of conversational English, the usage of 'what' and 'which' changes slightly according to the level of formality or informality involved. In casual conversation, the use of 'which' often becomes less strict, and 'what' is used more liberally instead. This laid-back usage, however, does not apply in formal contexts where the semantic rules of 'what' and 'which' hold strong.

'What' vs 'Which' in Formal Writing

Unlike in casual conversation, the semantic rules of 'what' and 'which' strictly apply in formal writing. This necessity for stricter adherence arises from the need for precision and clarity in formal communication, whether in academic, professional, or legal contexts. Hence, it is beneficial to understand the grammatical constructs involving 'what' and 'which' in formal writing contexts.

'What' and 'Which' in Non-Interrogative Contexts

While 'what' and 'which' primarily function as interrogative words, they also find use in non-interrogative contexts. These include relative clauses where 'what' takes on the role of both subject and object and 'which' features primarily in defining and non-defining relative clauses. Having a proper understanding of 'what' and 'which' usage in non-interrogative contexts can help improve overall English language proficiency.

Nuances of 'What' and 'Which'

Subtle Differences in Meaning with 'What' and 'Which'

Choice of 'what' or 'which' can sometimes subtly alter the meaning of a sentence. While 'which' can infer that the speaker has a particular answer in mind, 'what' does not imply this, thereby offering a broader range of potential responses. For instance, 'What is your favorite color?' solicits an unrestricted response, while 'Which of these is your favorite color?' asks for a choice among provided options. The understanding and manipulation of these subtle differences can result in enhanced communication effectively.

'What' and 'Which' in Imperative Sentences

'What' and 'which' also find expression in imperative sentences. In this case, 'which' is used when some choice is involved, whereas 'what' is used to ask for information in a general sense. For example, 'Tell me which book you like' invites a selection, but 'Tell me what book you are reading' solicits factual information. The correct use of 'what' and 'which' in imperative sentences can thus ensure better precision and communication capabilities.

'What' and 'Which' in Subject and Object Positions

Lastly, 'what' and 'which' have diverse applications in the subject and object positions in sentences. As a subject, 'what' introduces a sentence, but 'which' as a subject is comparatively rare and only seen in situations where the speaker wants the listener to select a specific option from a known list. On the other hand, both 'what' and 'which' can function as objects, but their usage depends on whether the range of options is open or limited. A grasp of this usage can further enhance English language efficiency.
