A clause is a constituent consisting of two parts: a subject and a predicate. The concepts of subject and predicate are probably already familiar to you from your earlier schooling. In terms of meaning, we can say that the subject is the part of the clause about which something is asserted, and the predicate makes that assertion. These definitions are vague, and eventually we will need to be more precise. We will describe a clause in terms of structure once we're better able to describe how that structure works.

(11) diag_6_2

Subject and predicate are both grammatical functions. The predicate is realized by a verb phrase, and in the most common case, the subject is realized by a noun phrase. Notice that in the diagram above, we indicate both the grammatical form (the phrase type) and the function. The two are separated by a colon. Thus our notation follows the pattern form: function.[1]

Labels like NP, VP, etc, tell us the structural form of a constituent. Form alone, however, does not tell us everything about how a constituent works in the sentence. We must also consider its function.

(7) Her dog chases rabbits.

For example, her dog and rabbits in (7) are both noun phrases, but they have different functions in the sentence. Although we haven't yet specified these functional roles, we can already see that each noun phrase has a different role in the sentence. The dog is doing the chasing, and the rabbits are being chased. The role of her dog is probably already familiar to you: it serves as the subject of this sentence. Rabbits plays a role known as the direct object, which we will study in the next chapter.

The constituent that we will see most is the phrase. A phrase consists of a single main word, called the head of the phrase, and other words that modify or give grammatical information about the head. These other words in the phrase are called the phrase's attributes. Informally, we might say that the head word is the main idea of the phrase.

(2) Russia's proposal at the conference

The phrase in example (2) is talking about a kind of proposal. Russia's and at the conference tell us what specific proposal we're talking about. Proposal, therefore is the head word.[1]

If we look at the components of a sentence, we can say that a sentence consists of a string of words. But if we look more closely, it's easy to see that the words aren't all equal. Instead, they occur in groups. Consider the famous opening sentence of Leo Tolstoy's Anna Karenina:

(1) All happy families resemble one another, but each unhappy family is unhappy in its own way.

It's not very helpful to think of the individual words in isolation. What, for example, is the relationship between each and resemble? In fact, they don't have a direct relationship. They are more closely related to other words in the sentence than they are to each other. We can appreciate some of this structure by dividing the sentence into some of its component parts.

To properly split an infinitive

Submitted by Karl Hagen
As many of you probably know, the prohibition against the split infinitive is one of the most notorious non-rules of English grammar. I say non-rule because even incredibly conservative books Like Fowler's essentially dismiss it as necessary for good writing. And yet some people are still afraid to insert an adverb between the infinitive marker to and the verb. Hence we find sentences like the following, from a legal memo just posted on Groklaw (emphasis added):

Before You Go Prescriptive

Submitted by Karl Hagen
We've all been there: you read a piece in a newspaper, book, blog, etc., and something about the writer's use of language annoys you. Perhaps you find a pronoun in the wrong case ("I found Alice and he waiting at the bar."). Perhaps you run across some strange word choice ("Mark consistently flaunted his parents' authority, returning well after his curfew."). In short, the writer has committed unspeakable barbarities upon the English language, and you are provoked. But before you unload your scorn on this poor, benighted soul who has assaulted your sensibilities, pause a moment to reflect.

An Old Grammar Joke

Submitted by Karl Hagen
[The protagonist of this joke doesn't need to be a Texan, but that's how the joke was originally told to me.] A Texan is visiting a friend at Harvard, and they agree to meet at the library. He's a bit lost, so he stops a passing student. Texan: "'Scuse me, could you tell me where the library's at?" Student: "Around here, we don't end our sentences with prepositions." Texan: "All right, could you tell me where the library's at, asshole?"
