Some of these question word sentences can look a bit like what we at Writelike describe as compound sentences:
- But I know how those things go.
- The light slanted wherever it hit the trees.
- It means you are challenging them when you stare at a gorilla.
These are all multiple events related together by a connector.
And honestly, there isn't really a problem with thinking about them that way.
But it's also useful to recognise the similarity in function between a question word clause like the "compound-like" sentences above, and a "definitely complex" sentence such as:
- Thanks to you, whoever has come to save us is doomed.
They all describe entities (things, people, places, times, qualities...) that are unknown.
GRAMMAR DIVE!
If you want the ins and outs of it, here's a grammatical explanation of what's happening.
Question words such as ‘what’ and ‘whoever’ are more than just connectors.
Imagine each of the clauses below without the question word—what would it sound like? And what grammatical function is the question word serving?
Standing in for a missing subject
- “Whoever has come to help us is doomed.”
This clause is missing an ‘actor’: we don’t know who has “come to help”. But English clauses need subjects to be grammatical. So, the question word in this clause stands in for a subject as well as functioning as a connector.
Standing in for a missing object
- “Whoever the hiking trail brought to its lip is doomed.”
This clause has a subject—the hiking trail—but the verb "brought" needs an object. “The hiking trail brought to its lip” sounds incomplete—it needs to bring someone or something. So this question word stands in for that object.
That said, do you notice something odd about the position of this question word object? Objects usually come after the verb, but connectors have to be at the start of a clause. Since question words are fundamentally connectors, they need to be at the start of the clause.
Functioning as an open-ended modifier
- “When you stare at a gorilla, it actually means you are challenging them.”
This clause has all the essential components—subject, verb group, objects. If you remove the word 'when', the sentence still makes sense, but it definitely needs a replacement connector, such as:
- “You stare at a gorilla, and it actually means you are challenging them.”
But we've lost something about time. We could add a non-connector time back in:
- "At breakfast you stare at a gorilla, and it actually means you are challenging them."
Again this makes sense, but now it's getting more specific and we've lost the sense of a general rule:
- “When you stare at a gorilla, it actually means you are challenging them.”
Here's what's happening: the question word is serving as both a connector between clauses and a modifier within the supporting clause. And rather than being a specific modifier (e.g. "at breakfast") it serves as a kind of open-ended modifier (e.g. "whenever").
And if you think back to all of our "compound"-like sentences, you'll notice that the question words are playing a modifier role in all of them:
- But I know how those things go.
- The light slanted wherever it hit the trees.
(Can you see why this would make them look like compound sentences, even though technically they are complex?)
The point of all this
Is really just to point out how question words are kind of iconoclastic and follow their own rules, like our favourite free-spirits, the adverbs. But they do as a group serve a specific function—as an open-ended stand-in for whatever.
