Why Should I Care about Interrogative Sentences?

Interrogative sentences are important. They're the tool for getting the information we want. Interrogative sentences are not as common as declarative sentences (ones that make statements), but they are the next most common sentence type. So, if you're learning or teaching English, it's essential to understand how they are formed.

If you're a native English speaker, then interrogative sentences are unlikely to be responsible for any serious writing errors. Nevertheless, here are two good reasons to think a little more carefully about interrogative sentences.

(Reason 1) Don't use a question mark after a non-question. (Beware indirect questions!)

Interrogative sentences (i.e., questions) are not responsible for serious errors among native English speakers, who understand how to form the three question types. By far the biggest issue related to interrogative sentences is writers thinking a non-question is a question and using a question mark.
  • I want to know if it's finished?
  • I wonder if I'll ever find my torch?
  • (These are not questions but statements. They should end in periods (full stops).)
This error typically occurs when the statement contains an indirect question. An indirect question is a direct question embedded inside a statement or another question. Here, the embedded direct questions are "Is it finished?" and "Will I ever find my torch?".

(Reason 2) Use a rhetorical question to raise a subject.

Rhetorical questions (i.e., ones that are not expected to elicit an answer) can be used to make a point or to introduce a subject.
  • When are you ever settled enough to have kids? (Actor Benedict Cumberbatch)
  • (This is a rhetorical question designed to make a point not to elicit an answer. It's an interesting way of saying "You are never settled enough to have kids.")
  • Is the Loch Ness monster dead?
  • (This is a rhetorical question designed to introduce a subject. Often used as titles, rhetorical questions are designed to pique the audience's interest.)
