Complex Sentences

Complex sentences are sentences composed of a Main Clause and one or more Embedded Clause.  These sentences allow speakers and writers to express more information in a single sentence while maintaining the fluidity that might be lost if those clauses were broken up into multiple sentences.

Embedded Clauses fulfill a certain part of speech within their Main Clause, taking the role of an adjective, adverb, or noun.  The details of forming a complex sentence depends upon the type of Embedded Clause used.

Intro to Clauses

First, it's important to understand what exactly a clause is. What are the core components of a clause? What's the difference between a clause and a sentence?

The following topics are sorted based on the type of Embedded Clause they feature: Relative (Adjectival) Clauses, Adverbial Clauses, and Content (Noun) Clauses.

Relative Clauses

aka Adjectival Clauses

Relative Clauses

Relative Clauses follow the nouns they modify. They begin with relative linkers that both refer to the key noun in the main clause and represent that noun in the embedded clause.

Advanced Relative Clauses

Once learners have a grasp on the basics of Relative Clauses, they should learn more of its complexities, especially A) the differences between non-restrictive and restrictive clauses, and B) more details and options for Relative Linkers.

Adverbial Clauses

Adverbial Clauses

Adverbial Clauses often follow the verb phrases (or noun phrases) they modify. There are multiple types of Adverbial Clauses; each serves its own function as prescribed by the conjunction (like a preposition) they start with.

Condition Clauses

Condition Clauses are a type of Adverbial Clauses. They represent cause and effect situations and generally fall within Unreal sentences.

Content Clauses

aka Noun Clauses

Reported Speech

Reported Speech is what we use to repeat what we or someone else said earlier (usually). That's expressed as a content clause, and the main clause of that sentence establishes that the Reported Speech is in fact reported.

Using 'That' with Reporting Verbs

Reported Speech often uses 'said' as the main verb of its main clause, but there are other Reporting Verbs one can use. The ones that are followed by 'that' are then followed by content clauses.
RECOMMENDATION: Visit the Reported Speech page first.

Indirect Questions

Indirect Questions include Reported Questions and Polite/Formal Questions. The two are used pretty differently, but they essentially have the same structure.

Wishes & Regrets

Wishes and Regrets are generally expressed as content clauses that are preceded by wish expressions like "if only" and "I wish".

General Notes

Colored Text

Our videos feature selective colored text.  Colors stand out and help students know what to pay attention to.  We’re rather consistent with our color choices so that students learn to expect certain things from certain colors.  We recommend using this same technique yourself.  Read our article to learn more.

Focus on Structure & Usage

Most of our methods are all about either sentence structure or usage. We touch on forms of individual words less often, and we hardly ever address infection or pronunciation. All five of these are important, but form and pronunciation tend to be more straightforward, so we let teachers decide for themselves how to present those. We dedicate our resources to the trickier stuff.

Working in Phrases

Most of the time when we say ‘noun’, we actually mean ‘noun phrase’, which typically includes determiners (like articles, possessives, and quantifiers) and sometimes adjectives.  We often do the same with verb strings; auxiliary verbs, ‘not’, and sometimes adverbs are included when we say ‘verb’.

Within the framework of a sentence, combining all those individual words into one block is generally helpful, as they act together to serve a single purpose.

American English

We mostly use American English, although most ESOL books primarily use British English.  We do this because our founder and lead content creator is American, so it’s what comes natural to him.  Just think of this as an excuse to teach your students some of the differences between British English and American English.
