Modality (1)

On the page The Verb Structure Circle, I discussed the four basic building blocks of the English verb: the simple forms 1 (so-called ‘simple present’) and 2 (so-called ‘simple past’) and the aspects continuous and perfect.

What this basic approach to English verb structures does not cover is modality. What is modality? If you have read the page mentioned above, you will remember that one of the main semantic features of the two ‘simple’ forms is factuality. We express things we believe to be true facts using the two simple forms.

What if we are uncertain of the reality, truthfulness, certainty or factuality of what we want to express? To take an example: We are not sure, for instance, where we want to go in a strange city (and we forgot our navigation system) and we are looking for the restaurant a friend recommended, so we say something like: It could be that one at the corner, or it might be the other one opposite, or maybe we are in the wrong street … in the latter case we are not using a modal to modify the lack of concrete knowledge (or factuality) of the location we are looking for, but the word ‘maybe’, thus expressing our uncertainty lexically. In the other cases, however, we are using ‘could’ (be) and ‘might’ (be) – two modal auxiliaries. Notice that in the sentences including a modal the verb – in this case ‘be’ – stays in infinitive form, whereas in the sentence without modal auxiliary the verb (‘be’ in main verb function) changes its form according to ‘person’ (in this case ‘we’ are).

Another example: Let’s say we are not sure what we would like to do today so we start considering different options. We could (notice the modal here) say something like:

We could go to the zoo or we could stay at home, or we could do nothing….

The suggestive nature of my proposition is expressed by the modal auxiliary could.

Or let’s say I have a problem and need some advice; somebody could say to me something along the lines of:

You could do X; or

I believe you should do Y; or

You might consider doing Z.

If you look at the structure of the verb phrase, in each case you have a modal auxiliary and the basic form/infinitive of the main verb. If we substitute ‘do X, Y, Z’ we could say something like:

You could give him a phone call

You should send her an email

You might think about talking to her

In each of the cases, time is not an issue, as the main focus is on giving advice or making a suggestion or, as in the following example, promising to do something.

Will and ‘ll

Will and it’s contracted form ‘ll also belong to the group of modals.

Let’s look at the example:

I‘ll give him a ring later.

Though the promised activity is in the future, we would not – linguistically – speak of a future tense here (will-future, as you find it in many course books). It lies in the nature of promises, suggestions, predictions and advice etc. that the activities, if fulfilled, lie some time in the future from now. Note: If I leave out ‘later’ in the example above and say ‘I’ll give him a ring’, it is implied by the form that I intend to do it right away; in fact, I am offering to do something right away by using ‘ll. (In most cases, native speakers would use the contracted form and not ‘will’ when offering to do something at the moment of speaking.)

The number of modal auxiliaries in English is restricted to eight or nine – depending on if you include ought to (more about ‘ought to’ in a moment).

We also have want to, need to, have to – but these are not categorized as modal auxiliaries. They do not modify the meaning of the verb, but are used to express the speaker’s attitude towards an activity, or the speaker’s opinion of someone else’s attitude:

I want to see (the film).                                  It is my wish or desire…

She needs to go (to the dentist tomorrow).    The speaker or ‘she’ believes in the necessity of a certain activity, in this case ‘going to the dentist’.

He has to leave (tomorrow).     ‘Has to’ expresses obligation: some force, inner or external, is behind the activity, there is no choice, something ‘has to’ be done.

The time reference with all three, like in the examples with modals, lies in the future; this distinguishes all examples above from those with verbs in the first or second form (‘simple present’ and ‘past tense’). The latter two express timeless or past factuality.

Something that has not happened yet, however, can not be or is (normally) not expressed in factual forms – unless I am totally certain that something will happen because it always happens or is on an agenda. When we talk about schedules and time-tables e.g. we (can) use the simple form to talk about a future event:

The train leaves tomorrow at …

The meeting starts at …

The three verbs ‘want to’, ‘have to’ and ‘need to’ behave slightly differently grammatically from modal auxiliaries as they have a second form and the ‘to’ as an inseparable component. However, the main verb also remains unchanged when in combination with one of the three (see examples above).

Ought to is somehow in between the two groups: it shares the meaning of the modal auxiliary should, but structurally resembles the other three as it also goes with ‘to’ – it differs from the latter three in that it has no second form; in this respect it is the same as the eight modal auxiliaries. (I personally have not integrated ‘ought to’ into my active vocabulary, and always considered it more British; to me it means exactly the same as ‘should’)

Concerning word order, the modal auxiliaries behave like the other auxiliaries DO, BE, HAVE and are very regular. If we want to form a question, we swap the auxiliary with the subject; if we want to negate, we add not or n’t to the modal just as we would to the respective forms of DO, BE and HAVE (DO I will treat in a separate post):

It will rain …..                             Will it rain…?

We shouldn’t go ….                 Should we go ….?

They might not come …           (Questions with ‘might’ are rather rare, and I have never heard or read mightn’t)

DO and HAVE are different from the modals in that they have a second form and a third person singular -s (like ‘want to’, ‘need to’, and ‘have to’); BE – as in many languages – is different from the others in that it changes more often according to person.

Some might ask if ‘could’ is the second form of ‘can’, or ‘would’ the second form of ‘will’. In some cases, the answer is ‘yes’; it depends on the meaning of ‘can/could’ and ‘will/would’ respectively. I will leave this for a separate post.
