33. Complex Example-Giving



Complex example-giving is naming a random member of an already-mentioned general class and adding information about it



Example-giving is naming one or more – but not all – of the members of a previously-mentioned category. For instance, cats or cats and dogs could be given as examples of the category name animals (for more on categories, see 162. The Language of Classification). Category members named as examples must not have been chosen because they are special in any way; they must be random (see 54. Sentence Lists 1: Incidental).

When we randomly name one or some of the members of a category, we may or may not say something about them. Adding this extra information is what I mean by “complex” example-giving. Here is an example:

(a) Many animal species have died out in the past. Dinosaurs, for example, disappeared 60 million years ago.

Here, dinosaurs is a member of the category animal species (that have died out), while 60 million years ago is something said about them (a more specific equivalent of the past). This post is about the language that is typically associated with complex example-giving. For language choices when nothing needs to be said about an example being given, see 1. Simple Example-Giving. For some ideas about why we give examples, see 96. Hedging 2: Lists and Predictions.



Unlike simple examples, complex examples do not allow much choice about the sentence where the class member is named: it is usually different from the sentence naming the class, as in (a) above. Often this new sentence is introduced with example-showing words, but not always: in research that I conducted in 19851, I found that around 30% of new-sentence exemplification had no example-showing language. In such cases, the meaning of exemplification is understandable just from the positioning of the example sentence after the one containing the class name. For more on how sentence positioning communicates meanings like exemplification, see 18. Relations between Sentences.

The example-showing language most commonly associated with complex example-giving is for example or for instance. Used like this, they are acting as connectors, like therefore and however (see 40. Conjunctions versus Connectors). Other words that can show complex examples are take, consider and imagine (see below), as well as most of the words that can also show simple examples. For more about how these latter can be used in complex example-giving, see 112. Synonyms of Connectors.

Because for example and for instance are connectors, they are usually found with a comma after them, and their position is flexible. These are very different features from those that they have in simple example-giving, where they are more like prepositions (see 84. Seven Things to Know about Prepositions). Note in particular that, while the connector use of for example (with complex examples) normally has a comma or full stop after it (as well as one before), the preposition use (with simple examples) generally has just a comma before.



The following are the main pitfalls to avoid:

Error 1: Incorrect Comma Use with “For Example” & ”For Instance”

It is easy to confuse the two different uses – connector and preposition – of these two expressions. As explained in the last section, complex example-giving needs the connector use (full stop/comma before and after).


Error 2: Everything Said in One Sentence

Two forms of this error are:

(b) *Many environmental problems result from the use of air pollutants, for example acid rain is caused by sulphur dioxide.

(c) *Many environmental problems result from the use of air pollutants, for example sulphur dioxide, which causes acid rain.

The first of these is incorrect because it breaks the full stop rule of “new verb, new sentence”. The new verb (is caused) can only stay in the same sentence as the old one (result) if there is also a joining device (see 30. When to Write a Full Stop). There is no joining device in (b): the words for example are a connector, not a joining device.

Sentence (c) is grammatically correct (the joining device is which) but not recommended because its form is very rare: writers of formal English prefer to give complex examples in a new sentence.


Error 3: “For Example”/“For Instance” in a Sentence without a Verb

It is possible to give the class member and the information about it in separate new sentences (see below), but not with for example or for instance, because they would then produce a sentence without a verb, like this:

(d) *Air pollutants cause many problems. For example sulphur dioxide. It leads to acid rain.


Error 4: Repetition of the Class Name with “it”

Sentence (d) cannot be corrected by simply changing the full stop after sulphur dioxide into a comma. The problem then is the repetition with it. Although conversational English allows this sort of same-sentence pronoun repetition, formal written English does not (see 24. Good & Bad Repetition).



Take and consider can be used instead of (or along with) for example/for instance in complex example giving, but only when the focus is on the information being given about the example, not on the example itself, which the reader is expected to know already. At least three sentences are needed:

(e) Air pollutants cause many problems. TAKE/CONSIDER sulphur dioxide. This leads to acid rain.

Here, the reader is expected to know already that sulphur dioxide is an example of an air pollutant, but not the problem that it causes. It is made the object of take/consider, and the information about it follows in a new sentence. This kind of division does not lead to a sentence without a verb, as it does with for example/for instance (see [f] above), because take and consider are themselves verbs (used in the “imperative” form – see 128. Imperative Verbs in Formal Writing).

Examples that are a simple noun phrase like sulphur dioxide above can follow either take or consider. However, noun phrases beginning with a question word, such as how writers can show disagreement, seem more likely to need considerNote also that the example-repeating pronoun in the third sentence in (e) is this and not it. The reason is that the example (sulphur dioxide) is the object of take/consider, not the subject (see 28. Pronoun Errors).

The verbs TAKE and CONSIDER can only be used with complex examples. However, they can sometimes be replaced by an example-giving expression that can also show a non-complex (simple) example in a new sentence, especially is a case in point:

(h) Air pollutants cause many problems. Sulphur dioxide IS A CASE IN POINT. It leads to acid rain.

Note that the pronoun in the third sentence here is it instead of this, reflecting the fact that the preceding example is now the subject of its sentence.

IMAGINE is different from the other two verbs in that it can be followed by either a noun or that and a full statement, like this:

(i) Driving at high speed is sometimes necessary. Imagine that you are on a fast road. …

SUPPOSE, which always needs a following that, is possible here too. Now here is an exercise that might help some of the above points to be better understood and remembered. 



In this exercise, you have to find example-giving that should have a full stop before it, and then identify the verb(s) in it that make the full stop necessary. Answers are given below.

1. Many countries besides Spain are Spanish-speaking for example Venezuela.

2. Some numbers below 25 can be exactly divided by at least five other numbers for instance 12 can be divided by 1, 2, 3, 4 and 6.

3. Essay writing involves particular skills for example grouping and sequencing points in a logical way.

4. There are numerous requirements for giving a successful oral presentation for example using signpost language promotes audience attention.

5. Building more roads is desirable for various reasons for instance it can reduce accidents.

6. Languages can be learned with the help of special books for example dictionaries, which assist vocabulary acquisition.

7. Nature is an influential source of technological innovation consider the wings of birds these have facilitated aircraft design.


ANSWERS: The new-sentence example giving should be in nos. 2 (can be divided), 4 (promotes), 5 (can reduce) and 7 (consider and have facilitated = two example sentences). Note that verbs with –ing or which (e.g. grouping in 3 and which assist in 6) do not by themselves require a new sentence.

  1. Sir,I read this post,and I found it much helpful. I have a confusion in that can I use “suppose” or “Let us consider” instead of take or consider for giving complex example.If these words cannot be used instead of take/consider then please state the use of those words.Actually I want to know the correct use of “suppose” or “Let us consider”.Please give one example of each and instances for using it.Thanks for the contribution that you provide us to learn English.

    • You are right: “suppose” and “let us suppose” do introduce complex examples. They need different grammar from “take” and “consider”, though: a following “that” (explicit or “understood”) plus a verb with its subject, like this: “Moral decisions are not always easy. SUPPOSE (THAT) you are very hungry. If you saw … etc”. There is also the verb IMAGINE. It can be used before either an object noun or “that” + verb.

  2. No.6. Languages can be learned with the help of special books. For example, dictionaries assist in vocabulary acquisition. [ am i right?]

    • Thanks for your question, Daniel; it raises a useful point. In answer, your sentence is correct grammar (except that you added an unnecessary “in” after “assist” – there is no “in” in the original sentence). The point is that the original sentence, with a comma added before “for example” and the word “which” included, is also correct. This is because “which” (or “who”) in an example joins a verb in the example (here “assist”) onto the previous sentence. So there are two ways to give this example: either with a comma before and “which” included, or with a full stop before and no “which” (as you have done it). Your way is probably better English style. Note that examples with “which” break the normal rule that a complex example must be in a new sentence.

  3. part b. if i say, many academic subjects are influenced by ancient Greek thinkers. For example, philosophy is one of them. Asiimwe Denis

    • Interesting question, as many ask the same. Your suggested sentence is grammatically correct, but not good writing. The reason is repetitiveness: “for example” and “is one” mean the same thing, so you are saying it twice. You need a verb in this new sentence, so “one is” is possible by itself but “for example” is not.

  4. according to me,the answer to number 7 is
    Nature is an influential source of technology innovation.Consider the wings of birds these have facilitated aircraft design.
    What do you think?

    • Thanks for your feedback, Ronald. Your answer is almost correct. What is missing is the full stop after “birds”. Remember that using “take” and “consider” requires the example-giving to be in two sentences.

    • No, I don’t think there is any other word that can replace “which” here. You could not use “that” because of the comma before “which” (“that” must have no comma before it). The next post on the site (no 34) will be about commas with “which” and “that”.
