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.

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?

A2 | Elementary | Pre-intermediate

CEFR A2 is the second level in the Common European Framework of Reference for Languages, often called elementary or pre-intermediate. If you're at this stage, you've moved beyond the basics of A1 and can handle simple, real-life communication — but you're still building the foundations you'll need for B1 and beyond.

What can an A2 learner do?

At A2, you can:

• Understand everyday expressions related to familiar topics — personal details, family, shopping, work, and your local area.
• Communicate in routine situations that involve a simple, direct exchange of information (e.g. ordering food, asking for directions, making small talk).
• Describe your background and immediate environment in simple terms — where you live, what you do, what you need.
• Read and understand short, simple texts like signs, menus, timetables, and brief personal messages.

Key grammar at A2

At this level, you're expected to be comfortable with several core grammar areas:

• Past simple and past continuous — talking about completed actions and actions in progress in the past.
• Present perfect — connecting past events to the present (I've visited London twice).
• Basic modal verbs — expressing ability, permission, necessity, and possibility (can, must, should, have to).
• Common question forms — both simple and slightly more complex (How long have you lived here?).
• Articles and determiners — using a/an/the correctly, along with words like some, any, few, little.
• Basic conditionals — first conditional and simple uses of if and wish.

You're also expanding your vocabulary through collocations (natural word pairings like make a decision or take a break) and learning to use gerunds and infinitives with common verbs.

How A2 differs from A1 and B1

Compared to A1, A2 learners can do more than just produce isolated phrases — you can link simple sentences and participate in short conversations. Compared to B1, you're still relying on familiar contexts and predictable language; handling unexpected topics or expressing opinions in detail comes at the next level.

Self-check: If you can describe your daily routine, talk about past experiences, and handle a basic conversation at a shop or restaurant — but struggle when the topic gets abstract or unfamiliar — you're likely at A2.
