That is not to say that I think that it is impossible to have core meanings, it's just that there are three components of modality - epistemic, deontic and dynamic. Deontic and dynamic modality is sometimes lumped together as root modality but does seem to involve two different types of modality as evidenced by the difference between "must" and "have to".
The examples that Metal listed are all epistemic modality. Now not all modals carry all three types of modality, but where they do there can be a minimum of three core meanings. Although I would like to note that deontic meanings are less abstract and therefore more likely to emerge first. Historically, I think that this is the case.
I wish I could say that I know what Andy means here, but I'm afraid he is way over my head.
Instead of using some big words here and assuming that everyone knows what they mean, at least as they apply to linguistic analyses, maybe it would be useful to get into some detail about what Andy’s terms might mean.
I hasten to confess, here, that I don’t know what they mean. Really, I had to check several dictionaries, and do some thinking to come up with some ideas that seem reasonable to me. So what follows is the meanderings of a non-professional in a very messy area of an inexact science, but let’s see where they go, and whether some of you can buy what I’m selling.
Modality, to begin with, refers to, I believe, a speaker’s ability to separately comment on the nature of the proposition being advanced in the main part of the sentence in which the modal appears. Keeping in mind that sentences are influenced, which is to say that their
meaning is influenced as well as, in some cases, their form, by the context in which they appear, modality is often expressed with the use of what we regularly call
“modals” or
“modal verbs” or (my preference)
“modal auxiliaries.” This is not the only way modality can be expressed, but it is an important way, and the one under discussion here. There is a fundamental difference between a sentence like
She runs fast and another one like
She can run fast. The first is a statement which is represented by the speaker as a truth or fact (whether or not it is actually true). The second sentence, containing
can, uses that word for the speaker to posit his momentary, present time, personal view of the information contained in the rest of the sentence.
Can is only used here as an example; any of the nine modal auxiliaries can be used, but always in the same place in the sentence, and always with the same intent: to comment on the viability of the proposition in the sentence. The nature of the comment is determined by which particular modal auxiliary is chosen, and its core meaning, as well as by the context surrounding the sentence, which moulds and develops the core meaning.
Andy tells us that there are three types of modality, and he names them
epistemic, deontic and dynamic. (I suppose he got these labels from somewhere else; indeed I have seen them before on other websites, and Andy has mentioned them earlier on this site, but candidly, I have never understood what they mean). These are the words I had to look up and think about. It seems to me that the label
epistemic simply means that the modal device attempts to
justify the piece of knowledge that the main proposition states. It characterizes that proposition as an
opinion advanced by the speaker, as opposed to, for instance, a generally accepted truth. When one says,
“They are home now”, one represents it as truth…period. Of course, for all of you who will object that it still is only the opinion of the speaker, the “truth” may turn out to be false. The point is that the speaker is using certain forms of language to show us he is
presenting it as a truth. (I suppose we can take it or leave it). However, when that speaker says,
“They will be home by now”, he comments, with
will, that the notion of ‘They’ being home is his opinion, and the modal auxiliary used there represents to us that he is expressing the proposition as an opinion. He is justifying his knowledge that ‘They’ are home. This is what I think is meant by
“epistemic modality”. Correct me if I’m wrong here, please.
Deontic denotes that the modality, epistemic though it may be, deals with the ideas of
permissibility or ability. So epistemic modality and deontic modality are not separate kinds or types of modality, but rather deontic modality is a subdivision of the epistemic variety. When I say,
“ You may leave if you’re finished with the test”, or,
“Rabbits can run faster than turtles”, I am expressing not only epistemic modality, but also deontic modality. At least this is what I am thinking now. Again, correct me if I’m wrong in this.
Dynamic modality may be different than epistemic modality. Here, dynamic refers to the expression of the force of personality of the speaker. When my wife says to my son,
“You will get up now and you will get to school on time!” , she is displaying the force of her personality and authority by stressing the modal auxiliaries there. Dynamic modal auxiliaries are not normally used in contracted form. The full form, as well as vocal stress (or the use of italics or some similar device in writing), expresses the force desired.
OK. Some of you are better trained than I am in this area. What I’d like to hear from you is whether I’m on the right track, or way off base.
