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?

Interrogative Sentence / Clause

An interrogative sentence asks a question and hence ends with a question mark. In speech, it almost universally ends in a rising inflection. Its effort is to try to gather information that is presently unknown to the interrogator, or to seek validation for a preconceived notion held. Beyond seeking confirmation or contradiction, sometimes it is approval or permission that is sought as well, among other reasons one could have for posing a question. The one exception in which it isn't information that is needed, is when the question happens to be rhetorical. While an imperative is a call for action, an interrogative is a call for information.

• What do you want?
• Are you feeling well?

Subject

The subject is the part of a sentence or clause that tells you who or what the sentence is about. It typically comes before the verb and controls the verb's form — meaning the verb must agree with the subject in number and person.

How to identify the subject

The subject is usually a noun, pronoun, or noun phrase that performs the action or is described by the predicate.

• She works at a hospital.
• The old bridge collapsed during the storm.
• Running every morning keeps me healthy.

The verb agrees with the subject: She works (singular) vs. They work (plural). This subject-verb agreement is one of the most reliable ways to find the subject.

Self-check trick: Ask "Who or what + verb?" to locate the subject. "Who works at a hospital?" → She. That's your subject.

Types of subjects

• Simple subject — the core noun or pronoun alone: Dogs bark.
• Complete subject — the simple subject plus all its modifiers: The two large dogs next door bark every night.
• Compound subject — two or more subjects joined by a conjunction: Coffee and tea are available.

Tricky cases

Sometimes the grammatical subject isn't the "doer." In passive sentences, the subject receives the action:

• ❌ Thinking the subject must be the doer: "The window" broke itself?
• ✅ The window was broken by a ball. (The window is the subject, but the ball did the breaking.)

English also uses dummy subjects — words like it or there that fill the subject position without carrying real meaning:

• It is difficult to learn French.
• There are three problems with this plan.

In the first example, the "real" subject (the thing that is difficult) is to learn French, but grammatically it holds the subject slot. These are sometimes called expletive subjects.

Why it matters

Getting the subject right is essential for subject-verb agreement, choosing correct pronoun forms (he vs. him), and building clear sentences. Misidentifying the subject is one of the most common sources of grammar errors, especially with longer or inverted sentences.

Object

Traditional grammar defines the object in a sentence as the entity that is acted upon by the subject. There is thus a primary distinction between subjects and objects that is understood in terms of the action expressed by the verb, e.g. Tom studies grammar—Tom is the subject and grammar is the object. Traditional theories of sentence structure divide the simple sentence into a subject and a predicate, whereby the object is taken to be part of the predicate. Many modern theories of grammar (e.g. dependency grammars), in contrast, take the object to be a verb argument like the subject, the difference between them being mainly just their prominence; the subject is ranked higher than the object and is thus more prominent.

The main verb in a clause determines whether and what objects are present. Transitive verbs require the presence of an object, whereas intransitive verbs block the appearance of an object. The term complement overlaps in meaning with object: all objects are complements, but not vice versa. The objects that verbs do and do not take is explored in detail in valency theory.

Types

Various object types are commonly acknowledged: direct, indirect, and prepositional. These object types are illustrated in the following table:

The descriptions "entity acted upon" and "entity indirectly affected by the action" are merely loose orientation points. Beyond basic examples such as those provided in the table, these orientation points are not much helpful when the goal is to determine whether a given object should be viewed as direct or indirect. One rule of thumb for English, however, is that an indirect object is not present unless a direct object is also present. A prepositional object is one that is introduced by a preposition. Despite the difficulties with the traditional nomenclature, the terms direct object and indirect object are widespread.

The term oblique object is also employed at times, although what exactly is meant varies from author to author. Some understand it to be an umbrella term denoting all objects (direct, indirect, and prepositional), whereas others use the term to denote just a prepositional object.

Syntactic Category

While the typical object is a pronoun, noun, or noun phrase, objects can also appear as other syntactic categories, as illustrated in the following table:

Identification

A number of criteria can be employed for identifying objects, e.g: The object follows the subject. Languages vary significantly with respect to these criteria. The first criterion identifies objects reliably most of the time in English, e.g.

Fred gave me a book.

• a. A book was given (to) me. — Passive sentence identifies a book as an object in the starting sentence.
• b. I was given a book. — Passive sentence identifies me as an object in the starting sentence.

The second criterion is also a reliable criterion for isolating languages such as English, since the relatively strict word order of English usually positions the object after the verb(s) in declarative sentences.

The third criterion is less applicable to English, though, since English lacks morphological case, exceptions being the personal pronouns (I/me, we/us, he/him, she/her, they/them).

Verb Classes

Verbs can be classified according to the number and/or type of objects that they do or do not take. The following table provides an overview of some of the various verb classes:

Ergative and object-deletion verbs can be transitive or intransitive, as indicated in the following table:

The distinction drawn here between ergative and object-deletion verbs is based on the role of the subject. The object of a transitive ergative verb is the subject of the corresponding intransitive ergative verb. With object-deletion verbs, in contrast, the subject is consistent regardless of whether an object is or is not present.

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.

B1 | Intermediate

B1 is the intermediate level of the Common European Framework of Reference for Languages (CEFR). It marks the point where you move beyond survival English and start expressing yourself with real independence — describing experiences, explaining opinions, and handling everyday situations without a script.

What a B1 user can do

At this level, you're expected to:

• Understand the main points of clear, standard speech and writing on familiar topics — work, school, travel, hobbies.
• Handle most travel situations in English-speaking environments.
• Produce simple connected text on topics you know or care about.
• Describe experiences, events, hopes, and plans, and give brief reasons and explanations for your opinions.
• Communicate in routine tasks that require a straightforward exchange of information.

What B1 grammar looks like

B1 is where grammar starts to get more layered. You're not just forming basic sentences anymore — you're combining ideas, using different tenses with more precision, and starting to handle structures like the passive voice, modal verbs for necessity and possibility, and gerunds vs. infinitives. You're also expected to build complex sentences with linking words and dependent clauses.

Typical B1 grammar areas include:

• Future tenses — distinguishing will, going to, and the present continuous for future plans
• Passive voice — The report was written yesterday.
• Modal verbs — You should apply early. / She might be late.
• Used to — I used to live in Berlin.
• Verb patterns — knowing whether a verb takes a gerund, an infinitive, or both (I enjoy reading vs. I decided to leave)

What B1 doesn't mean

B1 speakers still hesitate, make grammatical errors, and sometimes struggle with less familiar topics. That's normal. The key difference from A2 is that you can keep a conversation going and get your point across even when things aren't perfect. The step up to B2 involves handling more abstract topics, understanding nuance, and producing more complex, accurate language.

Self-check: Can you tell a friend about a recent trip — what happened, what you liked, and what you'd do differently — without switching to your native language? If yes, you're likely operating at B1 or above.
