Clause and Sentence

A sentence may consist of single or multiple clauses. Clause and sentence encompases terms used with both clauses and sentences.

Phrase

In everyday speech, a phrase may be any group of words, often carrying a special idiomatic meaning; in this sense it is synonymous with expression. In linguistic analysis, a phrase is a group of words (or possibly a single word) that functions as a constituent in the syntax of a sentence, a single unit within a grammatical hierarchy. A phrase typically appears within a clause, but it is possible also for a phrase to be a clause or to contain a clause within it.

Conjunction

In grammar, a conjunction is a part of speech that connects words, phrases, or clauses that are called the conjuncts of the conjoining construction. The term discourse marker is mostly used for conjunctions joining sentences. This definition may overlap with that of other parts of speech, so what constitutes a "conjunction" must be defined for each language. In English a given word may have several senses, being either a preposition or a conjunction depending on the syntax of the sentence (for example, "after" being a preposition in "he left after the fight" versus it being a conjunction in "he left after they fought"). In general, a conjunction is an invariable grammatical particle and it may or may not stand between the items conjoined.

The definition may also be extended to idiomatic phrases that behave as a unit with the same function, e.g. "as well as", "provided that".

A simple literary example of a conjunction: "the truth of nature, and the power of giving interest". (Samuel Taylor Coleridge's Biographia Literaria)

Conjunctions may be placed at the beginning of sentences: "But some superstition about the practice persists".

Examples

• "But she must give security that she will not marry without royal consent, if she holds her lands of the Crown, or without the consent of whatever other lord she may hold them of."—Magna Carta (1215), translated into modern English
• "But we, or our chief justice if we are not in England, are first to be informed."— Magna Carta (1215), translated into modern English
• "And for the support of this Declaration, with a firm reliance on the protection of divine Providence, we mutually pledge to each other our Lives, our Fortunes and our sacred Honor."
• "But in all such Cases the Votes of both Houses shall be determined by Yeas and Nays, and the Names of the Persons voting for and against the Bill shall be entered on the Journal of each House respectively."—United States Constitution (1787)
• "And the Congress may by general Laws prescribe the Manner in which such Acts, Records and Proceedings shall be proved, and the Effect thereof."—United States Constitution (1787)
• "And this power has been exercised when the last act, required from the person possessing the power, has been performed."—United States Supreme Court Judgment (1803)
• "But, in a larger sense, we can not dedicate, we can not consecrate, we can not hallow this ground." Abraham Lincoln's Gettysburg Address (1863)
• "Yet, if God wills that it continue until all the wealth piled by the bondsman's two hundred and fifty years of unrequited toil shall be sunk, and until every drop of blood drawn with the lash shall be paid by another drawn with the sword, as was said three thousand years ago, so still it must be said "the judgments of the Lord are true and righteous altogether."Abraham Lincoln's Second Inaugural Address (1865)
• "So the inquiries can coexist, though there is much overlap between them."
• "And it appears that it was this latter factor which underlay the dismissal of the appeal by the majority. But it seems to me that the question of whether it is fair, just and reasonable is better considered against the background of whether a sufficiently proximate relationship exists."
• "But the earlier decisions in Pratap Narain Singh Deo and Valsala K. were not brought to the notice of the Court in the two later decisions in Mubasir Ahmed and Mohd. Nasir."
• "And now we have Facebook and Twitter and Wordpress and Tumblr and all those other platforms that take our daily doings and transform them into media."
• "So any modern editor who is not paranoid is a fool".
• "And strikes are protected globally, existing in many of the countries with labour laws outside the Wagner Act model."

Adverb

An adverb is a word that modifies a verb, adjective, determiner, clause, preposition, or sentence. Adverbs typically express manner, place, time, frequency, degree, level of certainty, etc., answering questions such as how?, in what way?, when?, where?, and to what extent?. This function is called the adverbial function, and may be realized by single words (adverbs) or by multi-word expressions (adverbial phrases and adverbial clauses).

Adverbs are traditionally regarded as one of the parts of speech. However, modern linguists note that the term "adverb" has come to be used as a kind of "catch-all" category, used to classify words with various different types of syntactic behavior, not necessarily having much in common except that they do not fit into any of the other available categories (noun, adjective, preposition, etc.)

Sentence

A simple sentence consists of only one clause.
A compound sentence consists of two or more independent clauses.
A complex sentence has at least one independent clause plus at least one dependent clause.
A set of words with no independent clause may be an incomplete sentence, also called a sentence fragment.
A sentence consisting of at least one dependent clause and at least two independent clauses may be called a complex-compound sentence or compound-complex sentence.

1. I like trains.
2. I don't know how to bake, so I buy my bread already made.
3. I enjoyed the apple pie that you bought for me.
4. The dog lived in the garden, but the cat, who was smarter, lived inside the house.
5. What an idiot.

Sentence 1 is an example of a simple sentence.
Sentence 2 is compound because "so" is considereda coordinating conjunction in English, and sentence 3 is complex.
Sentence 4 is compound-complex (also known as complex-compound). Example 5 is a sentence fragment.

The simple sentence in example 1 contains one clause.
Example 2 has two clauses (I don't know how to bake and I buy my bread already made), combined into a single sentence with the coordinating conjunction so.
In example 3, I enjoyed the apple pie is an independent clause, and that you bought for me is a dependent clause; the sentence is thus complex.
In sentence 4, The dog lived in the garden and the cat lived inside the house are both independent clauses; who was smarter is a dependent clause.
Example 5 features a noun phrase but no verb. It is not a grammatically complete clause.

Vocabulary for Upper Intermediate/B2 English Level

Vocabulary for Upper Intermediate/B2 English level refers to the set of words and phrases that learners at this level are expected to know and use in the language. These learners have a solid foundation of vocabulary and grammar and are able to communicate effectively in most situations. At this level, learners are expected to have a good command of a wide range of vocabulary and grammar structures, and to be able to use them to express themselves in a clear and detailed way. They are also expected to understand and use more complex vocabulary and idiomatic expressions, such as phrasal verbs and collocations, to communicate nuanced ideas and express themselves in a more sophisticated way. Additionally, learners at this level are expected to have a good understanding of vocabulary related to a variety of topics such as work, school, leisure, and current events. They are also expected to be able to understand and use vocabulary from different specialized fields, such as business, science, and technology. B2 level learners are expected to have a very good command of the language, and this level is considered as the level of a proficient user of the language.

Collocations

Collocations are combinations of words that are frequently used together in a particular order, forming a natural-sounding expression. These word pairs or groups often sound more natural to native speakers than other possible combinations of the same words. Understanding collocations is important for language learners because they help you sound more fluent and natural when speaking or writing.

B2 | Upper Intermediate

B2, or Upper Intermediate, is the fourth level on the CEFR scale. It marks the point where you move from "getting by" to genuinely comfortable communication — handling complex topics, expressing nuanced opinions, and understanding most of what you read or hear in real-world contexts.

What a B2 user can do

At this level, you're expected to:

• Understand complex texts on both concrete and abstract topics, including technical discussions in your own field.
• Follow extended speech and lectures, even when the structure isn't entirely clear, as long as the topic is reasonably familiar.
• Interact fluently and spontaneously enough that conversations with native speakers flow naturally — without strain on either side.
• Produce clear, detailed text on a wide range of subjects, using connectors and cohesive devices to build well-structured arguments.
• Explain and defend a viewpoint on a topical issue, weighing the advantages and disadvantages of different options.
• Recognize implicit meaning — reading between the lines in demanding, longer texts.

What B2 grammar looks like in practice

B2 is where grammar stops being about isolated rules and starts being about flexibility and precision. You're expected to control structures like:

• Advanced conditionals and mixed conditionals — moving beyond simple if-clauses to express hypothetical and counterfactual meaning.
• Passive voice in varied tenses and contexts, not just present and past simple.
• Reported speech with correct sequence of tenses, including backshifting and reporting verbs.
• Participle clauses and the distinction between participles and gerunds.
• Comparative and superlative structures beyond basic -er/-est, including double comparatives and qualifying expressions.

Errors still happen at B2, but they rarely cause misunderstanding. The goal is controlled, flexible use of language across social, academic, and professional settings.

How B2 fits in the CEFR progression

B2 builds directly on the foundations of B1 (Intermediate) and prepares you for C1 (Advanced). Many university entrance exams, professional certifications, and immigration requirements target B2 as the minimum standard.

Self-check: If you can read a newspaper editorial, follow most of a TED talk without subtitles, and write a clear essay arguing a position — you're likely operating at B2.
