Indirect Speech

Verbs often undergo tense changes in indirect speech. This commonly occurs in content clauses (typically that-clauses and indirect questions, when governed by a predicate of saying (thinking, knowing, etc.) which is in the past tense or conditional mood.

In this situation the following tense and aspect changes occur relative to the original words.

Changes to past:

• "I like apples." → He said that he liked apples.
• "We are riding." → They claimed that they were riding.
• "You have sinned." → I was told that I had sinned.

Changes to past perfect (and sometimes past progressive to past perfect progressive):

• "They finished all the wine earlier." → He thought they had finished all the wine earlier.

This change does not normally apply, however, when the past tense is used to denote an unreal rather than a past circumstance (e.g., expressions of wish, conditional sentences and dependent clauses):

• "I would do anything you asked." → He said he would do anything she asked.

Changes to conditional, also referred to as future-in-the-past (i.e. will/shall changes to would/should):

• "The match will end in a draw." → He predicted that the match would end in a draw.

The modals can and may change to their preterite forms could and might :

• "We may attend." → She told us that they might attend.

Verb forms not covered by any of the above rules (verbs already in the past perfect, or formed with would or other modals not having a preterite equivalent) do not change. Note that application of the above rules is not compulsory; sometimes the original verb tense is retained, particularly when the statement (with the original tense) remains equally valid at the moment of reporting:

• "The earth orbits the sun." → Copernicus stated that the earth orbits the sun.

Note also that the above tense changes do not apply when the verb of saying (etc.) is not past or conditional in form; in particular there are no such changes when that verb is in the present perfect: He has said that he likes apples.

Word Order

The primary word orders that are of interest are

• the constituent order of a clause, namely the relative order of subject, object, and verb;
• the order of modifiers (adjectives, numerals, demonstratives, possessives, and adjuncts) in a noun phrase;
• the order of adverbials.

Constituent word order is defined in terms of a finite verb (V) in combination with two arguments, namely the subject (S), and object (O).

There is a difference between grammatical word order and natural word order. In many languages, topicalization and questions can change the grammatical word order.

Examples

A: [Kate loves who/Who does Kate love?] (SVO/OSV)
B: [She loves Mark/Mark is who she loves.] (SVO/OSV)

In the (A) sentences, the first one is used when putting emphasis on who Kate loves, and the second is used with more of a quizzical tone. English uses stress and tone to emphasize different aspects of the sentences, which can also change the word order, as shown above.

In the (B) sentences, the first one is more likely to be used by a native English speaker. The second sentence is grammatical as well, but less likely to be said in natural speech. This is because English uses the SVO structure in regular sentences, but is able to answer questions using the same structure that was used in the sentence.

In English, you can change the word order depending on what you want to emphasize.

Questions

Like many other Western European languages, English historically allowed questions to be formed by inverting the positions of verb and subject. Modern English permits this only in the case of a small class of verbs ("special verbs"), consisting of auxiliaries as well as forms of the copula be. To form a question from a sentence which does not have such an auxiliary or copula present, the auxiliary verb do (does, did) needs to be inserted, along with inversion of the word order, to form a question. For example:

• She can dance. → Can she dance? (inversion of subject she and auxiliary can)
• I am sitting here. → Am I sitting here? (inversion of subject I and copula am)
• The milk goes in the fridge. → Does the milk go in the fridge? (no special verb present; do-support required)

The above concerns yes-no questions, but inversion also takes place in the same way after other questions, formed with interrogative words such as where, what, how, etc. An exception applies when the interrogative word is the subject or part of the subject, in which case there is no inversion. For example:

• I go. → Where do I go? (wh-question formed using inversion, with do-support required in this case)
• He goes. → Who goes? (no inversion, because the question word who is the subject)

Note that inversion does not apply in indirect questions: I wonder where he is (not *... where is he). Indirect yes-no questions can be expressed using if or whether as the interrogative word: *Ask them whether/if they saw him*.

Negative questions are formed similarly; however if the verb undergoing inversion has a contraction with not, then it is possible to invert the subject with this contraction as a whole. For example:

• John is going. (affirmative)
• John is not going. / John isn't going. (negative, with and without contraction)
• Isn't John going? / Is John not going? (negative question, with and without contraction respectively)

Tag questions are formed with a special verb and pronoun subject: isn't it?; were there?; am I not?

Present

Present tense is used, in principle, to refer to circumstances that exist at the present time (or over a period that includes the present time) and general truths. However the same forms are quite often also used to refer to future circumstances, as in "He's coming tomorrow" (hence this tense is sometimes referred to as present-future or nonpast). For certain grammatical contexts where the present tense is the standard way to refer to the future, e.g., conditional sentences and dependent clauses. It is also possible for the present tense to be used when referring to no particular real time (as when telling a story), or when recounting past events (the historical present, particularly common in headline language). The present perfect intrinsically refers to past events, although it can be considered to denote primarily the resulting present situation rather than the events themselves.

The present tense has two moods, indicative and subjunctive; when no mood is specified, it is often the indicative that is meant. In a present indicative construction, the finite verb appears in its base form, or in its -s form if its subject is third-person singular. (The verb be has the forms am, is, are, while the modal verbs do not add -s for third-person singular.)

Past

Past tense forms express circumstances existing at some time in the past, although they also have certain uses in referring to hypothetical situations (as in some conditional sentences, dependent clauses and expressions of wish). They are formed using the finite verb in its preterite (simple past) form.

Certain uses of the past tense may be referred to as subjunctives; however the only distinction in verb conjugation between the past indicative and past subjunctive is the possible use of were in the subjunctive in place of was.

Note also that in certain contexts past events are reported using the present perfect.

Future

English is sometimes described as having a future tense, although since future time is not specifically expressed by verb inflection, some grammarians identify only two tenses (present or present-future, and past). The English "future" usually refers to a periphrastic form involving the auxiliary verb will (or sometimes shall when used with a first-person subject). There also exist other ways of referring to future circumstances, including the going to construction, and the use of present tense forms. For particular grammatical contexts where the present tense substitutes for the future, see conditional sentences and dependent clauses. For discussion and comparison of the various ways of making future reference in English, see going-to future.

For specific uses of future constructions formed with will/shall, see future.

Future-in-the-past

A "future-in-the-past" tense (or form) is sometimes referred to. This takes essentially the same form as the conditional, that is, it is made using the auxiliary would (or sometimes should in the first person).

This form has a future-in-the-past meaning in sentences such as She knew that she would win the game. Here the sentence as a whole refers to some particular past time, but would win refers to a time in the future relative to that past time.

Clause

A clause is a grammatical unit built around a verb that typically contains a subject and a predicate. Understanding clauses is essential because they are the core building blocks of every sentence you read, write, or speak.

What makes a clause?

At minimum, a clause needs a verb (the predicate) and, in most cases, a subject — the person or thing the verb says something about. The predicate can also include objects, complements, and modifiers.

• She laughed. — subject (she) + verb (laughed)
• The manager approved the budget yesterday. — subject + verb + object + modifier

Sometimes the subject is left out. This happens regularly in imperative sentences and non-finite clauses:

• Sit down. — no visible subject, but "you" is understood
• Walking home, I noticed the shop was closed. — the -ing clause has no stated subject

Types of clauses

There are two main types:

• Independent clause (also called a main clause) — can stand on its own as a complete sentence. It contains a finite verb.

  • I missed the bus.

• Dependent clause (also called a subordinate clause) — cannot stand alone and needs an independent clause to make sense.

  • Because I overslept — incomplete on its own

Combine them and you get a complex sentence:

• I missed the bus because I overslept.

A simple sentence has one independent clause. More complex sentences combine independent and dependent clauses in various ways.

Quick check: If you can remove a group of words from a sentence and it still has a subject + finite verb and makes sense on its own, that group is likely an independent clause.

Why clauses matter

Recognizing clause boundaries helps you punctuate correctly, avoid run-on sentences, and build more varied, natural-sounding writing. Once you can spot where one clause ends and another begins, sentence structure becomes much easier to manage.

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.
