What is a sentence?

Most of the time, we can ‘hear’ whether or not we have written a ‘proper’ sentence because it makes sense and it sounds right. For this reason, we can usually see that the following, for example, are not proper sentences:

  • The book on the bookshelf
  • The torrential rain
  • A very long discussion

But why are these not sentences, apart from the fact that they don’t look or sound like sentences?

Well, a sentence must always include a verb and in most cases will also include a subject.

If you are not sure what a verb is, find out more about verbs here.

What is a subject?

The subject in a sentence is the person or thing that the sentence is about or the person or thing doing something.

So, let’s see how we can make the examples above into sentences.

We can change the book on the bookshelf to:

I put the book on the bookshelf.

You can see we have added the subject ‘I’ and the verb ‘put’.

We can change the torrential rain to:

They walked in the torrential rain.

We have added the subject ‘they’ and the verb ‘walked’.

We can change a very long discussion to:

The ministers ended a very long discussion at midnight.

We have added the subject ‘the ministers’ and the verb ‘ended’.

Punctuating your sentence

A sentence always starts with a capital letter and will end with a full stop, question mark or exclamation mark.

  1. A grammar maven asserts that something like this is a complete sentence: “A business consists of the following:” I mean, it’s got a subject, verb, and object, right? Yet it feels very incomplete….

    • Is this a trick question because it’s Friday afternoon? Surely a sentence has to make sense on its own to be truly a sentence? Or, as the Oxford Dictionary of English says, ‘A set of words that is complete in itself’. The example you cite is not complete. Right ingredients plus wrong recipe equals half-baked cake.

      • But a grammar maven asserted it was so! I don’t know [who/whom] to trust….

        • I think you should trust the following:

        • How about this: “A business consists of the idea”?

          • Or: “The villagers followed Jesus up the hill. He spoke to the following”?

            • Well, if — big if — the noun ‘following’ was followed by a full stop, that sentence would be fine.

          • “A business consists of the idea” is definitely not a properly constructed sentence because it doesn’t have a full stop at the end.

            • They don’t have full stops because I’m asking a question (of you). Add the full stops, if you wish, then let me know what you think.

              Michael Farrell

              • …even with a full stop I don’t think ‘A business consists of the idea’ is a sentence. And even if it was, what would be the point of writing it? No one would understand what you mean.


                26/03/2010 at 4:32 pm

                • I’ll keep playing, then: “A business consists of the idea at its core.” [Ed: Note full stop.?.]

                  • That’s just a horrible gobbledegook-type sentence that would need re-writing.


                    26/03/2010 at 4:41 pm

                    • But correct grammar and good writing are independent — like health-department scores at a restaurant and the quality of the cooking.

  2. Agreed. You can have perfect grammar yet write badly. But the opposite can never be true.
