To establish whether a question is valid, we can establish whether there exists a valid statement that the question stems from.
In Standard English, to turn a statement into a binary question, we need to follow one step:
- Perform subject-auxiliary inversion.
For example to turn the statement
This vehicle is a van.
into a question, we need to move the subject (this vehicle
) after the verb (is
):
Is this vehicle a van?
In some cases, we need to introduce an auxiliary verb instead. To turn this statement:
This vehicle looks cute.
into a question, we need to introduce the auxiliary verb do
(which will take the form does
to accommodate the singular first grammatical person of this vehicle
):
Does this van look cute?
In Standard English, there are two ways to describe the appearance of an object.
- An objective way, which we use when we want to understand the looks of something descriptively. For example, because we're trying to find that object based on its looks. This typically takes a noun. For example:
The vehicle looks like a van.
- A subjective way, which we use to express our opinion or impression of an object. This typically takes an adjective. For example:
The vehicle looks cute.
In Standard English, to turn a statement into a non-binary question, we need to follow these steps:
- Turn the statement into a binary question.
- Remove the word we intend to ask about.
- Place a corresponding WH question word at the beginning of the sentence.
For nouns, we use the "what" question word. For adjectives, we use the "how" question word.
Let's do this with our two statements. Please note the second step is intermediary so it will not always make sense semantically, but it's required grammatically.
The vehicle looks cute.
- Does the vehicle look cute?
- Does the vehicle look?
- How does the vehicle look?
The vehicle looks like a van.
- Does the vehicle look like a van?
- Does the vehicle look like?
- What does the vehicle look like?
How does it look like?
