There are three types of relativizers used in English to introduce relative clauses: zero or null relativizers,
wh-relativizers, and the
that-relativizer.
Comparative distribution of null and overt relativizers Relativizers have been analyzed to be optional in certain languages and are variably omitted in the
English language. Such relativizer omission, or use of the null or zero variant of relativizers, does not pattern uniformly in English and has been predicted to be conditioned and constrained by a number of linguistic and social factors. These social factors and the potential influence of age, gender, and education have been minimally explored and seem to exhibit a lesser effect on relativizer omission.
Linguistic constraints, such as sentence structure and
syntactic position of the relativizer,
main clause construction type, lexical specificity of the head NP, type of antecedent, and the adjacency, length, and grammatical subject of the
relative clause have been implicated as having more significant influence on the patterning of relativizer omission in Canadian English. The omission of relativizers tends to occur more frequently in conversation than in formal writing.
Distribution with subject and object relative clauses The syntactic position or function of the relativizer in the relative clause is a major determiner for the choice of relative marker. The null relativizer variant is more common in object than subject relative clauses. 3) I have friends
that are moving in together. (subject) 4) That's one thing
that I actually admire very much in my father. (direct object) 5) Everyone's kinda used to the age group
[Ø] they work with. (object of preposition)
Informational content of the main clause determines distribution There is a preference for null relativizers when a
main clause that is informationally light is directly
adjacent to the
relative clause. For example: 6) It's just kinda something
[Ø] I noticed recently. 7) They get values and stuff like that from church
that they might not get at home. In this example, the main clause 'it's just kinda something' provides little
semantic information and it is adjacent to the relative clause 'I noticed recently'. As such, it is thought that the main clause and the relative clause are processed together as a unitary processing chunk that is functioning like a single statement, which results in a null relativizer.
Distribution with empty head noun phrases Empty head
noun phrases, which are not lexically specific and which index generic groups or sets, have been correlated with the use of the null relativizer. Examples of empty noun phrases include words like
all,
way,
time, etc. 8) All
[Ø] she wants to do is sleep. 9) She held onto all those jewelry boxes
that everybody made for her when we were kids. Unique head
noun phrases, which include
superlatives and
nouns with the words
only and
first, also take the null relativizer. For example: 10) That's the only place
[Ø] you can go at night. 11) That's the first compliment
[Ø] I've got in a long time. 12) That was the worst job
[Ø] I ever had. 13) You have a home here
that you could rent.
Length of the noun phrase determines distribution Longer head
noun phrases often co-occur with an overt relativizer, whereas shorter noun phrases are more likely to co-occur with a null relativizer. For example: 14) This pair of suede pants
that I got. 15) The weight
[Ø] I should be at. In these examples, the first sentence contains a longer noun phrase ('This pair of suede pants') in comparison to the second sentence, which contains a very short noun phrase ('The weight'). Thus, it is observed that the sentence containing the longer noun phrase also contains the relativizer 'that', whereas the sentence with the shorter noun phrase has a null relativizer.
Definiteness of the noun phrase determines distribution Null relativizers have been found to be correlated to the definiteness of the nominal antecedent. For example: 16) I don't think you have the dedicated teacher
that I had. 17) And it was a guy
[Ø] she worked with for a few years. The first sentence contains a definite noun phrase, whereas the second sentence contains an indefinite noun phrase which co-occurs with the null relativizer.
Distribution with relative clause pronominal subjects When the grammatical subject of a relative clause is a pronoun, it is more likely that the relativizer will be omitted. When the subject of a relative clause is a full noun phrase, the overt relativizer will be retained. For example: 18) I have two cats
[Ø] I'd like to turn in to the Humane Society. 19) Do you remember exactly the road
[Ø] I'm talking about? 20) That was one of the things
[Ø] he did when he was living elsewhere. 21) I always go to my girlfriends 'cause there's stuff
that your parents just don't need to know.
Distribution of overt English relativizers The overt relativizers of Modern English include the words
"which," "what," "when," "where," "who," "whom," and
"whose", and these can be referred to within linguistics as "
wh-words". These are officially classified as
relative pronouns, but can be referred to as "
wh-relativizers" in instances where their function is to introduce a
relative clause. The other overt relativizer of Modern English is the word
"that", which can be referred to as the "
that-relativizer" where it introduces a relative clause. There is some debate as to whether to classify it as a relative pronoun like the wh-words, a
subordinating conjunction, or a
complementizer. The distribution of the different types of English relativizers varies depending on several factors.
Fused relative clauses Fused relative clauses, sometimes referred to as "free" relative clauses, are different from most other types of relative clauses in that there is no nominal antecedent to which the relative clause refers. In many cases, the relativizers of English are relative pronouns, meaning that they are in
coreference with a noun that precedes them in the sentence. This nominal function is "fused" with the relative clause in free relatives, and this leaves the relativizer without an overt entity to which it can refer. For example: 22) I wonder
what inspired them. 23) I wonder
whose dog died. There is no noun preceding the relative clause in these cases, and that is why it is said that this noun's function is "fused" with the relative clause.
Grammatical function of the relativized nominal determines relativizer case form Where there are different
grammatical case forms of a relativizer, the case form that surfaces will depend on the
grammatical function of the noun that appears previously (known as the nominal antecedent) within the relative clause itself. The only examples in Modern English of this phenomenon are the forms "who" and "whom". "Who" surfaces when it refers to a noun that is the
subject of the relative clause, and "whom" surfaces when it refers to a noun that is an
object of the relative clause. However, speaker judgments vary as to whether it is grammatical for "who" to surface when it is referring to an object of the relative clause. Since, depending on speaker judgments, either only "whom" or both "who and "whom" can grammatically introduce a relative clause referring to an object, there is an "m" in brackets on the end of the relativizer in example (25) below. • Subject antecedent 24) The person
who visited Kim • Object antecedent 25) The chairman listened to the student
who(m) the professor gave a low grade to
Animacy of the antecedent determines distribution Only certain relativizers can introduce clauses that refer to human antecedents, and similarly, only certain relativizers can introduce clauses that refer to non-human antecedents. "Who", "whom", and "whose" can only refer to human antecedents, "which", and "what" can only refer to non-human antecedents. "That", however, can refer to both human and non-human antecedents. To exemplify: • Human antecedent 26) The Pat
that I like is a genius 27) The Pat
who I like is a genius 28) The only person
that I like
whose kids Dana is willing to put up with is Pat • Non-human antecedent 29) Every essay
that she's written
which I've read is on that pile 30) Every essay
which she's written
that I've read is on that pile
Restrictiveness of the relative clause determines distribution Restrictive relative clauses have
semantic properties which make them necessary to prevent the sentence from being ambiguous. They are used in cases where the context that surrounds the sentence is not sufficient for the distinction between the potential nominal antecedents. Both
wh-relativizers and the
that-relativizer can be used to introduce restrictive relative clauses. Nonrestrictive relative clauses add extraneous information that is not vital for the listener or reader's understanding of which aforementioned noun is being referenced; or in other words, which noun is the nominal antecedent. Commas mark nonrestrictive relative clauses, and only the
wh-relativizers can be used to introduce them. To exemplify: • Restrictive sentences: 31) He has four sons
that became lawyers 32) The soldiers
who were brave ran forward • Nonrestrictive sentences: 33) He has four sons,
who became lawyers 34) The soldiers,
who were brave, ran forward
Finiteness of the relative clause determines distribution In non-finite clauses (clauses in which the verb is left unconjugated), the relativizer appears as an object of preposition, or in other words, directly after a preposition in the sentence. These relative clauses appear to be introduced by the preposition itself, but they are actually introduced by both the preposition and the relativizer, since these two grammatical particles form a "prepositional phrase"; and it is this phrase that introduces the clause. For example: 35) A yard in
which to have a party 36) The baker in
whom to place your trust 37) A student *
who to talk to us just walked in Note that (37) is ungrammatical because the relativizer introduces a non-finite relative clause, but it is not contained within a propositional phrase. ==In other languages==
