What Is a Clause?

A clause is a syntactic unit containing a subject and a predicate (typically a finite verb).

Comparison: - Phrase: the tall soldier — no finite verb, not a clause - Clause: the soldier fights — subject + finite verb = clause


Clause Types: Independent vs. Dependent

Type Definition Example
Independent (main) clause Can stand alone as a sentence The soldier fights.
Dependent (subordinate) clause Cannot stand alone; depends on a main clause …because he was ordered to

Independent Clauses

An independent clause expresses a complete thought and can be a sentence on its own.

English examples: - The dog barked. - She wrote a letter. - Rome fell in 476 AD.

Dependent Clauses

A dependent clause cannot stand alone. It is introduced by a subordinating conjunction or relative pronoun.

English examples: - …because he was tired (adverbial clause) - …who wrote the letter (relative clause) - …that she would arrive (noun clause)


English Clause Structure

Basic Clause Patterns

English has several basic clause patterns, determined by the verb type:

Pattern Structure Example
SV Subject + Verb Birds sing.
SVO Subject + Verb + Object The cat caught the mouse.
SVC Subject + Verb + Complement She is a doctor.
SVA Subject + Verb + Adverbial He lives in London.
SVOO Subject + Verb + Indirect Object + Direct Object She gave him a book.
SVOC Subject + Verb + Object + Object Complement They elected her president.
SVOA Subject + Verb + Object + Adverbial She put the book on the table.

Key: - S = Subject - V = Verb - O = Object - C = Complement - A = Adverbial

Parsing English Clauses

Example 1: The old professor gave his students a difficult assignment.

Element Function Notes
The old professor Subject (NP) head = professor
gave Verb past tense, ditransitive
his students Indirect Object (NP) recipient
a difficult assignment Direct Object (NP) thing given

Pattern: SVOO

Example 2: The committee appointed her chairperson.

Element Function Notes
The committee Subject (NP)
appointed Verb past tense
her Direct Object (NP) person appointed
chairperson Object Complement (NP) role assigned

Pattern: SVOC


Types of Dependent Clauses

1. Adverbial Clauses

English Spanish French Latin German Greek
adverbial clause oración subordinada adverbial proposition subordonnée circonstancielle Adverbialsatz ἐπιρρηματικὴ πρότασις

An adverbial clause modifies the verb of the main clause, answering questions like when?, where?, why?, how?, or under what condition?

Types of Adverbial Clauses

Type Introducing Words Example
Time when, while, before, after, since, until, as soon as When the bell rang, we left.
Place where, wherever I’ll go wherever you go.
Reason/Cause because, since, as She stayed home because she was ill.
Purpose so that, in order that He studied hard so that he would pass.
Result so…that, such…that He was so tired that he fell asleep.
Condition if, unless, provided that If it rains, we’ll stay inside.
Concession although, though, even though Although he was tired, he continued.
Comparison as, than, as…as She runs faster than I do.
Manner as, as if, as though He acted as if he knew everything.

Adverbial Clauses in Latin

Latin uses the subjunctive mood in many adverbial clauses:

Type Conjunction Mood Example
Purpose ut (positive), nē (negative) Subjunctive Vēnit ut vidēret. (He came to see.)
Result ut Subjunctive Tam fessus erat ut dormīret. (He was so tired that he slept.)
Cause (alleged) cum Subjunctive Cum aeger esset, nōn vēnit. (Since he was ill, he didn’t come.)
Concession cum, quamquam Subj. / Indic. Cum fessus esset, labōrābat. (Although tired, he worked.)
Condition (real) Indicative Sī pluit, domī manēbō. (If it rains, I’ll stay home.)
Condition (unreal) Subjunctive Sī dīves essem, domum emerem. (If I were rich, I’d buy a house.)
Time cum (circumstantial) Subjunctive Cum Rōmam vēnisset, ad Caesarem iit. (When he arrived at Rome, he went to Caesar.)

Adverbial Clauses in Greek

Greek also uses moods to distinguish clause types:

Type Conjunction Construction Example
Purpose ἵνα, ὡς, ὅπως Subjunctive (primary) ἦλθεν ἵνα ἴδῃ (He came to see.)
Purpose ἵνα, ὡς, ὅπως Optative (secondary) ἦλθεν ἵνα ἴδοι (He came to see.)
Result ὥστε Infinitive (natural) οὕτω σοφός ἐστιν ὥστε πάντας θαυμάζειν
Result ὥστε Indicative (actual) οὕτω σοφός ἦν ὥστε πάντες ἐθαύμαζον
Time ὅτε, ἐπεί Indicative ὅτε ἦλθεν, εἶδον αὐτόν (When he came, I saw him.)
Condition εἰ See conditional types below

2. Relative Clauses

English Spanish French Latin German Greek
relative clause oración de relativo proposition relative Relativsatz sententia relātīva ἀναφορικὴ πρότασις

A relative clause modifies a noun (the antecedent). It is introduced by a relative pronoun.

English Relative Clauses

Type Pronoun Example
Defining (restrictive) who, which, that The man who called is here.
Non-defining (non-restrictive) who, which My brother, who lives in Paris, is visiting.

Defining clauses are essential to identify the noun; non-defining clauses add extra information.

Latin Relative Clauses

The relative pronoun quī, quae, quod agrees with its antecedent in gender and number, but takes its case from its function in the relative clause.

Example: Puella quam vīdī pulchra est. (The girl whom I saw is beautiful.)

Word Analysis
Puella nom. sg. fem. — subject of main clause
quam acc. sg. fem. — direct object of vīdī
vīdī 1sg perfect — “I saw”
pulchra nom. sg. fem. — predicate adjective
est 3sg present — “is”

The relative pronoun quam is: - Feminine singular (agrees with puella) - Accusative (object of vīdī)

Greek Relative Clauses

Greek works similarly with ὅς, ἥ, ὅ:

Example: ὁ ἀνὴρ ὃν εἶδον σοφός ἐστιν. (The man whom I saw is wise.)

Word Analysis
ὁ ἀνήρ nom. sg. masc. — subject of main clause
ὅν acc. sg. masc. — object of εἶδον
εἶδον 1sg aorist — “I saw”
σοφός nom. sg. masc. — predicate
ἐστιν 3sg present — “is”

3. Noun Clauses (Complement Clauses)

English Spanish French Latin German Greek
noun clause oración sustantiva proposition complétive Inhaltssatz ὀνοματικὴ πρότασις

A noun clause functions as a noun — it can be a subject, object, or complement.

Types of Noun Clauses in English

Type Example
That-clause I know that she is coming.
Wh-clause (indirect question) I wonder who wrote this.
If/whether-clause I don’t know whether he will come.
To-infinitive clause I want to leave.
-ing clause I enjoy reading books.

Latin Indirect Statement (Accusative + Infinitive)

Latin uses the accusative and infinitive construction for reported speech and thought:

Example: Dīcō eum venīre. (I say that he is coming.)

Word Analysis
Dīcō 1sg present — “I say”
eum acc. sg. masc. — subject of infinitive
venīre present infinitive — “to come”

Tense in the infinitive is relative to the main verb: - Present infinitive = same time as main verb - Perfect infinitive = before main verb - Future infinitive = after main verb

Latin Analysis Translation
Dīcō eum venīre. present inf. I say he is coming.
Dīcō eum vēnisse. perfect inf. I say he came / has come.
Dīcō eum ventūrum esse. future inf. I say he will come.

Greek Indirect Statement

Greek uses several constructions:

Verb Type Construction Example
Verbs of saying ὅτι/ὡς + indicative λέγει ὅτι ἔρχεται (He says that he is coming.)
Verbs of thinking accusative + infinitive νομίζω αὐτὸν ἔρχεσθαι (I think he is coming.)
Verbs of perceiving accusative + participle ὁρῶ αὐτὸν ἐρχόμενον (I see him coming.)

Conditional Sentences

Conditional sentences (“if…then” constructions) are complex enough to warrant their own chapter. They involve careful coordination of mood and tense across all six languages.

See Chapter 6A: Conditional Sentences for full coverage of: - The four English conditional types (zero, first, second, third) - Spanish, French, and German conditionals - Latin conditional types (simple, future vivid/less vivid, contrary-to-fact) - Greek conditional types with the particle ἄν - Mixed conditionals - Parsing worked examples
