9. Reading Obstacles 5: Double Negatives

When two negative words are used together, readers sometimes struggle to see the resultant positive meaning.

MEANING AND TYPES OF DOUBLE NEGATIVE

A double negative is a pair of negative words that combine together to make a positive meaning. The two words may be both the same (e.g. not … not … ) or different. Here are some common examples:

(a) (SAME NEGATIVE USED TWICE) It is not normal not to want to be loved.

(b) (TWO DIFFERENT NEGATIVES) It is not impossible to become a millionaire.

The first example means it is normal to want to be loved; the second that it is possible to become a millionaire.

One situation where a double negative is likely to be used is when a negative statement is the established topic of a discussion. For example, (a) might be said in a discussion about not wanting to be loved, (b) in one about the difficulty of becoming a millionaire. The second negative is then added in order to be negative about the established negativity. A common reason for being negative in this way is when one disagrees with someone else’s negative statement (for more on disagreement, see 152. Agreeing & Disagreeing in Formal Contexts).

Another reason for using a double negative might be in order to make a subtle distinction between it and the seemingly equivalent positive. Consider this:

(c) Dogs are not averse to chocolate.

Averse to means “not fond of” (see 175. Tricky Word Contrasts 6, #6). However, the negative of this does not necessarily mean the full opposite “fond of”. As with most adjectives, it also covers the possibility of a middle position: neither liking nor disliking (see the discussion of on the contrary in 20. Problem Connectors). As a result, not averse to is weaker than fond of. In the same way, not impossible and not atypical are probably weaker than possible and typical, merely suggesting that impossibility/atypicality can, in rare instances, be overcome.

Note, finally that two negatives in English sometimes reinforce each other rather than cancel each other out (see 69. How Computers Get Grammar Wrong 2). However, that is a feature of informal or non-standard varieties, and is not normal in academic and professional writing.

THE DIFFICULTY OF DOUBLE NEGATIVES IN READING

The main reason why double negatives are a problem in reading seems to be the effort they require to work out their logic. The use of two different negative words may be particularly difficult, especially if one or both is “hidden” (see 13. Hidden Negatives). See how good you are at dealing with double negatives in the examples below. Try at least to identify the two negative words each time before you read the explanation.

Double  Negative 1

The most important point is that it is inconceivable that people could ever have developed their more complex tools without their ability to manipulate symbols and communicate with one another in symbolic languages.

This sentence gave students difficulty in a reading test. It means that making complex tools is only possible if symbols and language are used. The two negative words are inconceivable (= “not able to be imagined” or “not possible”) and without (= “not having”). Putting them together, “not possible … not having …” means “only possible … having …”. So the sentence could be rewritten “it is only possible that people could have developed their more complex tools by having the ability to use symbols and language.”

Double Negative 2

An important concern in decoding images should be that of undermining the ways in which dominant forms of visual representation reduce complex issues … to a few “recognisable” aspects which appear to constitute an acceptable totality.

This sentence was reported as difficult by a student from Japan (see my posted article What can learners tell us about their reading difficulties?). The two negative words are undermining and reduce. The first means “preventing” or “weakening”, the second “making less”. If you prevent something from being made less, you ensure it remains large. The writer seems to be saying that people who decode images should remember that complex issues have a larger number of aspects than the misleading few shown by the most popular images.

Double Negative 3

For example, if success and failure are to be judged solely by the quality of legislative reform …, the conclusion has to be that recognition of animals as anything other than commodities that exist mainly for human benefit has been limited.

This sentence was reported as difficult by a student from the Indian subcontinent. The use of a double negative is actually one of two comprehension problems here. The other is a lack of clarity about the link between legislative reform and recognition. The reader has to work hard to see that recognition means “recognition in legislative reform”.

The two negative expressions here are other than and limited. The first means “different from” (commodities) and hence is the same as “not” (commodities). It is helping to say something about animals. The word limited means “not much”, and is about recognition – there is not much of it. Thus, the double negative could be restated as “there is not much recognition that animals are not commodities”. In other words, animals are mostly recognised as commodities. What does that mean? It is a criticism. Legislative reform (i.e. changes in the law) sees animals only as commodities (things to trade in and exploit), when the writer thinks they should be respected as living things with rights of their own.

  1. Hey Paul,
    First of all, thanks for the crash course on double negatives. Although I consider myself as an advanced learner of the English language, I always have problems with double negatives sentences especially used in the academic journals and scientific reviews. I feel as if my brain shuts down. Could you please provide us with more examples of these kinds of sentences or recommend some readings to improve our comprehension.
    Best regards,
    HS

    • Thanks for your kind feedback. In response to your request, I would love to offer more examples, but I don’t have any – I would have to spend a lot of time trawling through texts to find some. Instead, I invite other readers to share any example sentences that they have come across. In addition, I can list for you some of the common combinations that make double negatives: “cannot fail to/cannot avoid” = will inevitably; “hardly lacks” = possesses in abundance; “with few gaps/omissions” = almost complete; “not unsurprisingly” = predictably;
