Dave Pippin's morphology whiteboard

This photo is a fine display of some morphological happenings from Dave's 7th grade class last spring.


The Do-Si-Do you can see there is mentioned in this lesson and came from John Horner's 7th graders at Whatcom Middle School.

Strand 1/Grammar – Lesson 10: Clauses (Subject-Auxiliary Inversion)

Another cool way to identify subjects is to use Subject-Auxiliary Inversion, which we already saw in Lesson 8. There, we saw that one way to turn a statement into a question is to move the auxiliary verb to precede the subject. Not only does this allow us to “discover” the auxiliary verb, but it will also “reveal” the subject. Remember, of course, that we make use of subjects all of the time in our speech, and have no problem doing so. But if we want a trick to consciously find the subject, simply make a question:

The chicken will eat the corn. → Will the chicken __eat the corn?

The portion of the sentence that the auxiliary verb inverts with or moves around will always be the subject, no matter how long or how short it is.

Mo is eating carrots. → Is Mo __ eating carrots?

The kid with a gigantic hat can’t see his friend.

→ Can the kid with the gigantic hat __ see his friend?

You can have students turn some sentences like these into questions by using SAI.

The kids should take their lunches on the fieldtrip.
The teacher visiting from Chicago will be our substitute next week.
The test on factors could be next week.
The man who talked with us on the bus about safety could also visit the classrooms.

Subject Auxiliary Inversion (SAI), like Tag Questions, will always pick out the subject of an independent clause, not a subordinate clause, so it will distinguish these from each other. Being able to easily pick out the subjects of our sentences will help ensure
• that each sentence has a subject, a required element of most academic writing
• that the subject “agrees with” the verb, if that’s something that you’re concerned about in your students’ writing
• that each independent clause has only one main subject, if you’re seeing comma splices/run-ons in students’ writing

I want to emphasize, though, that there are good reasons to talk about subjects other than simply dealing with issues in writing. That will come along for free, but it’s important to draw students’ attention to these phenomena. At the risk of repeating myself, subjects, like so many other features of language, are an aspect of the language that speakers already know about, that we have unconscious knowledge of. Figuring out the evidence for that is a useful exercise in scientific inquiry, and allowing students to “discover” the subjects that emerge beautifully when they make tag questions and perform SAI, reveals this knowledge.

A related lesson, which includes both Tag Questions and SAI, is here.

Strand 1/Grammar – Lesson 8: Main verbs and auxiliary verbs

As we move into the syntax of verb phrases, it’s important to discover some of the differences between verbs and auxiliary verbs. There are very few auxiliary (or helping) verbs, so it’s fairly straightforward to label them, but it’s instructive to really understand some of the ways in which the two categories differ. Then one can much more easily see how auxiliary verbs and non-auxiliary verbs behave in different ways in passive constructions, in progressive and perfect aspect, in representing the future tense, and so on.

Three of the ways in which auxiliary verbs differ from “main” verbs.
1) They occur before not and can contract with it.
Lulu has not eaten lunch yet.
Lulu hasn’t eaten lunch yet.
Compare to a sentence without an auxiliary – they’re terrible (as indicated by the *)!
*Lulu eats not lunch till noon.
*Lulu eatsn’t lunch.

2) Auxiliary verbs occur in tag questions.
Bobo is running the race, isn’t he?
Bobo hasn’t finished the race yet, has he?
Try to form a tag question on a sentence without an auxiliary – yuck.
*Bobo runs the race, runsn’t he?
*Bob finished the race in second place, finishedn’t he?

3) Auxiliary verbs move to the front of the sentence in a yes/no-question. We call this Subject-Auxiliary Inversion (SAI).
Are you guys singing at the concert? (You guys are singing at the concert.)
Have you been to New York? (You have been to New York.)
Main verbs can’t do that:
*Sing you at the concert?
*Like you New York?

Another difference between main verbs and auxiliary verbs is that auxiliary verbs are a closed class: new members are never added, while we add new verbs all the time.

But it’s a better idea to let the students discover these differences for themselves. They could discover that auxiliary verb have and main verb have have different patterns (and meanings). Since have can be both an auxiliary and a main verb, they can compare sentences such as the following to see how tag questions and SAI behave differently in the two sets.

She hasn’t been feeling very well.
The penguins have already been fed, haven’t they?
Have your friends left for the party?

I have four dollars left.
She has an injured elbow.
We have lots of energy.

They should also come up with all of the forms of be. Everyone knows these, of course, and uses them appropriately all the time, but students sometimes don’t realize that am, is, are, was, were, being, been are all forms of be. There’s a lesson on TeachLing on this.

The auxiliary verbs are have and be.
The "dummy" auxiliary verb is do. (See more on this below.)
And the modal auxiliaries are may, might, can, could, shall, should, will, would, must). These are different from these auxiliaries since they do not express tense or change their forms depending on the subject. They do, however, do all of the things in (1)-(3) above. We’ll return to a discussion of them.

There are related lessons on auxiliary verbs here and on auxiliary verbs and subjects here.

Dummy Do
When there is no auxiliary and the language needs one, a form of do is stuck in. Have them figure that out.

She likes eggs. - Make it negative. What happens?
She likes eggs. - Make it a question (both by SAI and a tag). What happens?

Be: Main Verb and Auxiliary Verb
Be is the only verb that has features of both auxiliary verbs and main verbs. It can be the only verb in a sentence (so act like a main verb), but also it does all of the things that auxiliary verbs do: precedes and contracts with not, moves to the front in questions, appears at the end in tag questions. It’s the last verb that can do all this, which other verbs could do in older forms of English. (“Think you a little din can daunt mine ears?” Shakespeare, The Taming of the Shrew; “Get thee to a nunnery.” Shakespeare, Hamlet)
