4 Introduction
Now on to part (II) of the handout. Having judged sentences (1-6) as either well-formed
or not, the students have a body of data upon which to draw. They can now proceed to use
this data—their judgments—to infer the principles that allowed them to make the judgments.
Unlike the first step, this step requires conscious analysis to formulate and fine-tune each
statement.
By dividing the sentences into two groups—those with * and those without—students can
start to arrive at the principles that govern tag questions. While this will take some trial and
error on their part (as well as reference to some terms they might not have used in a while—
like “auxiliary verb” and “antecedent of a pronoun”), with your help they can eventually
arrive at the following principles:
٪ The verb in a tag question must match the verb in the declarative (cf. 3, which uses a
present-tense verb in the declarative but a past-tense verb in the tag).
٪ The declarative and the tag cannot both be negative (cf. 4, which contains a negative
in both parts). (Although the data do not illustrate it, you might point out that a
If students are able to arrive at all of these principles, they will have done quite a bit for
the first day of class! The point to close with is they have been “doing” linguistics: trying to
formulate a conscious statement of the principles that allow speakers to judge sentences as
well-formed or not.
It is also worth pointing out that principles must be refined as new data is encountered—
for instance, ask students how they would form a tag question for the sentence Mary went.
Again, they will be able to formulate an immediate, uniform response (didn’t she?)—but it
violates one of the principles that accounted so well for sentences 1-6. A linguist’s work is
never done….

2. Mary has gone, hasn’t she?
