Part 1:

A good indicator of one’s English proficiency is the ability to use tag questions properly. But wait—we all know what “tag questions” are, don’t we all? Well, if some of us don’t or have already forgotten, the mini-question “don’t we all?” in the preceding sentence is what’s called a “tag question.” Some grammarians prefer to call it a “question tag,” and the whole statement inclusive of that mini-question the “tag question.”

For our purposes, however, we will refer to the mini-question as the tag question itself, or “tag” for short; we will not quibble over the terminology. The important thing is for us to fully appreciate and understand how native English speakers purposively use tag questions to get a quick confirmation or reaction from their listeners. With that, we should be able to form English tag questions ourselves with greater confidence, using them flawlessly to emphasize our thoughts and ideas and to elicit the desired response from our listeners.

Most of us will probably recall that tag questions generally follow a definite pattern: a positive statement is followed by a negative tag question, and a negative statement is followed by a positive tag question. Since tags are meant to be spoken, of course, it’s normal to use contractions of the negative forms of verbs either in the tag question or in the main statement itself.

Here’s a quick drill to jog our rusty memories about the grammar of tags. From the positive standpoint: “She is, isn’t she?” “They do, don’t they?” “We can, can’t we?” “You are Filipino, aren’t you?” And from the negative standpoint: “She doesn’t, does she?” “They don’t, do they?” “We can’t, can we?” “You aren’t Filipino, are you?”

We can see that the tag questions above are all of opposite polarity to that of the main statement. Also, we must keep in mind that without exception, the verb in a tag question always has the same tense as the verb in the main statement. (In speech, we must note here, there should always be a brief pause between the main statement and the tag question; in writing, this brief pause must always be indicated by a comma between the main statement and the tag question.)

Some of us will probably also recall that there are actually three ways of forming tag questions depending on the kind of verb used in the main statement.

First, if that verb is a form of the auxiliary verb “be,” the same form of that verb must be used in the tag question: “He is from Manila, isn’t he?” “We aren’t that bad, are we?” “They were of foreign origin, weren’t they?”

Second, if a main statement uses a modal such as “can,” “could,” or “should,” the same modal must be used in tag question: “She can dance, can’t she?” “They couldn’t do that, could they?” “We shouldn’t interfere in their affairs, should we?”

And third, if the main statement uses an active verb (instead of only an auxiliary verb), the appropriate form of the auxiliary verb “do” takes the place of that active verb in the tag question: “She loves you, doesn’t she?” “You take me for granted, don’t you?” “They played the part, didn’t they?” 

We will recall, too, that when a main statement has a proper name as subject, the tag question must use its pronoun instead: “Jennifer is doing well in Singapore, isn’t she?” “Manila isn’t the tourist capital in Asia these days, is it?” “Some Australians eat kangaroo meat, don’t they?” “Nestle is the biggest food company in the world, isn’t it?”

We must be aware, however, that some special cases of English-language tag questions don’t strictly follow the norms that we have just discussed. Here are two such tags that seemingly look and sound askew: “Let’s go out, shall we?” “Let’s not go out, shall we?”

Are those tags proper or not? Yes, they are. Even if those tags often raise the hackles of grammar purists, native English speakers accept and use both of them. The strictly grammatical to say “Let’s go out, shall we?” is, of course, “We’ll go out, shan’t we?”, but it sounds stiff and unnatural. Here are two natural-sounding alternatives that should sit in well among Filipinos: “Let’s go out, all right?” “Let’s go out, okay?”

Another notable special case involving tags is the whole range of statements that use “nothing,” “nobody,” and “no one” as their subject. In such cases, the statements should be considered of negative polarity, and their tag questions should be given a positive polarity: “Nothing came in the mail, was there?” “Nobody bothered you last night, was there?” “No one wants this, is there?”

We will take up other special cases and other fine aspects of tag questions in the next essay. (May 24, 2004)

Part 2:

We will continue our discussion of some notable departures from the usual positive-negative and negative-positive rule for forming tags, or those mini-questions purposively added by speakers at the end of their statements to get a quick confirmation or denial from their listeners. That general rule, we recalled, is that a positive statement should be followed by a negative tag, and a negative statement should be followed by a positive tag: “She’s winning, isn’t she?” “They’re not conceding, are they?” “We’ll not get into trouble for this, would we?”

Now, here are a few more tags that don’t scrupulously follow that polarity rule: “I’m correct, aren’t I?” (Not “I’m correct, amn’t I?” The awkward tag “amn’t I” is “am I not?” in contracted form, which is unacceptable grammar). “She’d better take it, hadn’t she?” (Not “She’d better take it, wouldn’t she?” The tag “hadn’t she?” is actually “had she better not?” in contracted form. That tag is the logical polar negative of the full statement “She had better take it,” where the operative verb form is “had better,” not “take.”). “This will do, won’t it?” (Not “This will do, willen’t it?”—which uses a tag that doesn’t exist in English. Conversely, the reverse-polarity statement will be “This won’t do, will it?”) 

Another exception about tags that bewilders many nonnative English speakers is this: the opposite polarity rule can actually be pointedly ignored when people want to strongly express sarcasm, disbelief, surprise, concern, shock, or anger. Take the following examples: “You think you’re indispensable, do you?” “Oh, you will really do that, will you?” “Oh, she really left him, did she?” “So you’re finally getting married, are you? That’s great!” (Or the contrary sentiment: “So she’s finally getting married, is she? The nerve!”) “And you think that’s amusing, do you?”

And then, as a mark of politeness, positive tags can also be routinely attached to positive requests: “Come here, will you?” “Do that, will you?” “Please hand me that screw driver, will you?”

When people use negative statements with negative tag questions, on the other hand, it is not necessarily bad grammar but a sure sign of the breakdown of civility or of downright hostility and combativeness: “So you don’t love me at all, don’t you?” “You really didn’t like the idea, didn’t you?” “So you don’t think my school is good enough, don’t you?” “So you didn’t want peace after all, didn’t you?” The negative tags emphasize the negativeness of the main statement to deliberately rile people or to make them feel guilty. They give vent to feelings of meanness.

Now, from experience, we all know that using negative statements with positive tag questions in the standard manner is the polite, socially acceptable way of asking for information or help. Such statements are particularly useful if we don’t know the people being addressed.

It is rude, for instance, to simply approach or accost on the mall someone we don’t know and ask, pointblank, “Where’s the women’s room?” The civilized way, of course, is to restate that question to the needed degree of politeness, depending on who is being addressed.

Here’s that same question said a little bit more politely, addressed to people of about the same age or social station as the speaker: “Do you know where the women’s room is?” (A tag question is not used in such cases.)

Now here it is in a polite, nonaggressive form, this time addressed to people older or of a higher social station than us: “You wouldn’t know where the women’s room is, would you?” (This time, the question form “Do you know...?” and the tag question that follows make the statement sufficiently deferential.)

Here are a few more patterns of negative statements with positive tag questions, the use of which should make us more pleasant, convivial people to deal with: “You don’t know of any job openings in your company at this time, do you?” “You don’t happen to know where the stock exchange building is, do you?” “You wouldn’t be willing to lose all that money in gambling, would you?” “You haven’t got anything to do with what happened, do you?” “You can’t spare me a thousand for my son’s tuition, can you?” “You can’t believe it that the woman’s leading the race, can you?”

The beauty of negative statements with positive tag questions is that they subtly prime up the listener’s mind either to accept the given idea or to decline it quickly and gracefully; in fact, refusing to answer the positive tag questions at all actually will make the person being addressed look rude and impolite. In this classic communication gambit of appealing to the other’s goodness of heart and of cushioning a possible blow to one’s self-esteem before that blow is even inflicted, nobody should lose face whatever the answer might be.

Surely one of the most slippery grammar trippers we’ll encounter in English is choosing between “like” and “such as” to form comparative statements or give examples. Which of them, for instance, is correctly used in the following two sentences?

(1) “Exemption from flight pre-boarding procedures like a thorough body search is usually granted to diplomats.”

(2) “Exemption from flight pre-boarding procedures such as a thorough body search is usually granted to diplomats.”

If you still haven’t figured out the correct usage, you may take comfort in the fact that you’re not alone in the predicament. The use of “like” and “such as” is actually considered correct in both sentences, but the choice between them has remained debatable all these years. We therefore need to carefully study both sides of the debate so we can put ourselves on more solid semantic footing regarding the usage.

Some grammarians insist that “such as,” which means “for example,” is the only correct usage in such constructions: “Exemption from flight pre-boarding procedures such as a thorough body search is usually granted to diplomats.” They maintain that “like” should never be used as a substitute for “such as,” arguing that “like” doesn’t convey the idea of giving an example at all. Instead, they say, “like” in this usage can only imply similarity, resemblance, or comparison, as in “Her pillow lips look like Angelina Jolie’s.”

Other grammarians are not as restrictive in their prescription for using “like” and “such as,” but they do recommend the following more precise usage for them:

(1) Use “such as” to introduce one or more examples that represent a larger subject, as in “Eduardo has a collection of vintage cars such as the 1955 BMW 507 and the 1915 Vauxhall”; and

(2) Use “like” to convey the idea that two subjects are comparable, as in “Alberto wants to be a vintage car collector like Ramon.”

Take note, though, that those same grammarians consider “like” to be a close semantic equivalent of “such as.” They are therefore not averse to substituting “like” for “such as” in the sentence given in Item 1: “Eduardo has a collection of vintage cars like the 1955 BMW 507 and the 1915 Vauxhall.”

On the other hand, they would find it unthinkable for anyone to substitute “such as” for “like” in the sentence given in Item 2 above. To them, the resulting sentence is unacceptable because it isn’t natural sounding or idiomatic: “Eduardo wants to be a vintage car collector such as Ramon.”

At any rate, “like” in modern spoken English has practically taken over the role of “such as” in comparative statements. The forms “such as” and “such...as” are now largely confined to formal writing. “Like,” in contrast, is now the preferred form for informal usage in which the example being given is offered not simply as an example but as the topic of the sentence itself, as in this case: "We are delighted to have a generous benefactor like Bill Gates." Using “such as” instead of “like” in such sentences must be firmly avoided, for it gives the sentence a false ring: “We are delighted to have a generous benefactor such as Bill Gates.”

In formal writing, we are well advised to distinguish carefully between “like” comparisons and “such as” comparisons. In a “like” comparison, only one person or object from the class is usually named, and that person or object is understood to be excluded from the group being discussed.

Take this example: “If you are a student taught by a brilliant mathematics teacher like Prof. Alberto Reyes, you would learn differential calculus in no time at all.” This comparison is about the possibility of students being taught by mathematics teachers whose brilliance is comparable to Prof. Alberto Reyes’s, with Prof. Reyes himself specifically excluded from the comparison.

On the other hand, in a “such as” or “such...as” comparison, one or several persons or objects can be named in the comparison, and all of those persons or objects are understood to be included in the group being discussed.

Take these two sentences:

“With highly capable mathematics professors such as Prof. Alberto Reyes and Prof. Eduardo Cariño handling the differential calculus classes, we can expect a much higher percentage of passing among the students.”

“With such highly capable mathematics professors as Prof. Alberto Reyes and Prof. Eduardo Cariño handling the differential calculus classes, we can expect a much high percentage of passing among the students.”

In both sentences, the comparison this time is about brilliant mathematics teachers as a class whose members include both Prof. Reyes and Prof. Cariño.

Now that we know how to clearly distinguish the semantic difference between “like” and “such as,” we should be able to use them from now on without fear of tripping in our grammar. (September 26, 2005)
