The question about why the infinitive ‘to use’ in ‘Which type of butter to use’ is in passive voice is an interesting one. In this article, we will explore the grammar behind this construction and why it appears this way. It’s a great opportunity to clarify the subtle differences in how English expresses ideas through passive constructions, especially in relation to infinitives and questions.
Understanding the Infinitive Form ‘To Use’
In English, the infinitive form of a verb is commonly used to express purpose or to form questions. For example, ‘Which type of butter to use?’ is asking about the type of butter intended to be used, with ‘to use’ functioning as the infinitive. In this sentence, the infinitive is not necessarily passive, but the misunderstanding might stem from how the question is structured.
It’s important to understand that the infinitive in this case doesn’t imply an action performed by the subject but rather what action is to be taken, which is why it’s often confused with a passive construction. Here, the subject is implied as the person who will be using the butter, rather than the butter itself being acted upon.
Passive Voice in Infinitives
The passive voice in English typically refers to situations where the subject of the sentence is the recipient of the action, rather than the one performing it. A classic example would be ‘The cake was eaten by the children.’ However, the structure ‘to use’ in ‘Which type of butter to use’ doesn’t imply the butter is the object being acted upon, which is the hallmark of the passive voice.
While ‘to use’ may seem like it could fit into a passive voice construction, it’s simply a standard infinitive that indicates the action someone is expected to take. It’s crucial to distinguish between a question structure and a passive construction, as this is what causes the confusion.
Understanding ‘What to do’ and ‘Which to do’
In expressions like ‘What to do’ or ‘Which to do’, the infinitive is used to ask about the options available or the best course of action. These constructions are not passive because they are asking for information about what action should be taken, not about who will take the action. For example, ‘What to do in case of an emergency?’ is asking for suggestions or actions, not who will do them.
In the case of ‘Which type of butter to use’, the construction is asking for clarification about which option (type of butter) should be selected for use, hence there is no passive meaning implied.
Why the Confusion Occurs
The confusion arises because of how questions are phrased. In many cases, the subject of the action is implied but not stated. In a sentence like ‘Which type of butter to use?’, the action is directed toward the butter, but the sentence is structured as a question about the action to be taken. This can create the illusion of a passive construction, when in fact it is simply an active question asking about a choice.
Summary
The construction ‘Which type of butter to use’ uses the infinitive form ‘to use’ to indicate an action or purpose, but it is not in the passive voice. The confusion stems from the fact that the sentence appears to talk about the butter being used, leading to a misunderstanding. In fact, it is a question about which butter should be chosen, and the use of the infinitive here is common in English to express purpose or intent.
