Modal verbs: how their use has declined in recent times

mustAs is well-known, English has a number of core modal verbs, including can/could, will/would, shall/should, may/might, and must. These make it possible for us to express meanings such as ‘possibility’, ‘necessity’, ‘obligation’, ‘permission’, and the like. In an earlier blog post I discussed the declining use of the modal verb must over recent decades. A very likely reason for this is that speakers have become less willing to appear to be telling others what to do, even in situations when they are entitled to do so.

What about the other modal verbs in English? The table below shows how their use has declined across the board in written and spoken British English between the 1960s and the 1990s:*

Notice first of all that the rate of change is different for the various modals in written and spoken English. For example, the use of can has increased more in spoken than in written English. This may be due to speakers using this verb more often to ask for permission than may, which has declined in use.

Let’s now take a closer look at shall, which is much more common in British English than in American English. Like must, it has also dropped dramatically in use. When used with first person subjects shall alternates with will:

I shall look into this.

I will look into this.

Is there a difference between these two ways of talking about a future event? From a stylistic point of view there is: the first of these alternatives sounds more formal, and is more likely to be used by older speakers. However, there is really no difference in meaning: both sentences are used to speak about a situation in the future.

Not everyone would agree with what I just wrote. Some writers would say that with first person subjects (I/we) will should be used to convey the idea of ‘wanting’, whereas shall should be used to talk about a neutral future. With other persons (he, you, they, etc.) shall should be used for promises/guarantees (Cinderella shall go to the ball), in ‘regulatory language’ (Students shall not enter the premises after midnight), or to express something that the speaker wants (You came for the action, and action you shall have). The journalist Simon Heffer explains the difference with a well-known anecdote in his book Strictly English (2012):

The Victorian schoolmaster had a way of impressing this distinction upon his charges, with the story of the boy who drowned: for he had cried out ‘I will drown, and no-one shall save me’.

Heffer regrets the fact that speakers no longer know how to use shall and will in the right way. Maybe it’s true that a useful distinction in English is lost. However, another way of looking at this development is to recognize that the language has changed in such a way that the difference between shall and will (other than in questions) is slowly disappearing because speakers no longer sense a meaning difference between these verbs. This would mean that speakers need only one verb, and it looks like will has won out. The increased use of will shown in the table above supports this hypothesis, but the increase is not as high as you would expect, so perhaps the table only offers a partial explanation for the trends in usage. What’s interesting is that the decline of shall is slightly higher in spoken English than in written English. This may well mean that the decline will spread in the future because changes in spoken language often make their way into written language.

  1. This article seems to confuse social change with linguistic change. The word “must” is still vibrant and in full use when you want to express that level of obligation. But as a social change, people may prefer to be less imperious and opt for a less abrupt phrase. That doesn’t mean the word “must” is falling out of use. It means that the occasions when a strong level of obligation needs to be conveyed are declining. I doubt the corpora (corpuses) of spoken English from the 1960s were as comprehensive as corpora of modern-day usage, so there seems to be some confusion here too.

    • Thanks for highlighting this, dj1969! You’re right, and if you refer back to one of the posts linked in the blog post, you’ll see that social change is mentioned: “Most likely as a result of our society becoming less hierarchical, speakers of English now tend to use different ways of making requests of others, without sounding too authoritarian.” Language change is a huge area, however, and it is impossible to cover it comprehensively in individual blog posts. Thank you for reading and engaging with the content – we hope that you continue to do so! If there is a particular subject you’d like us to post about in the future, please do let us know.
