Intermediate Grammar

Active voice and passive voice are two ways to build a sentence in English. In the active voice, the subject does the action: “Tom writes the email.” In the passive voice, the subject gets the action: “The email is written by Tom.” The passive is used when the action matters more.

In English, advanced logical connectors help link ideas in a clear and exact way. They can add information, show contrast, give a reason, show a result, or express a condition. Words like however, therefore, whereas, and provided that make speech and writing smoother.

An adverbial subordinate clause is a part of a sentence that gives extra information about the main action. It can show time, reason, condition, purpose, contrast, or result. It often starts with words like because, if, when, although, or so that. It cannot stand alone.

In English, the basic sequence of tenses is a rule that helps you choose the right verb tense in a sentence with a main clause and a subordinate clause. If the main verb is in the past, the other verb usually changes to a past tense too.

In English, complex comparative structures help you compare things in a more detailed way. You can show that two ideas change together, or that one thing is equal to, greater than, or smaller than another. They make your meaning clear, natural, and more exact.

In English, a complex sentence has one main idea and one dependent idea. The dependent part cannot stand alone. The two parts are often linked by words like because, if, when, although, or that. This helps you add detail and show cause, time, condition, or contrast.

In English, conjunctions are words that connect words, groups of words, or complete sentences. They help you add ideas, show contrast, offer a choice, give a reason, or explain a result. Common examples are and, but, or, and because. They make sentences smoother and easier to understand.

In English, direct and indirect speech are two ways to report what someone said. Direct speech gives the speaker’s exact words, usually in quotation marks. Indirect speech gives the meaning, often with changes to pronouns, verb tense, and time or place words.

In English, expressing cause and consequence shows why something happens and what happens next. We often use words like because, since, so, therefore, and as a result. Example: I was tired, so I went to bed early.

In English, expressing cause and consequence shows why something happens and what result follows. We often use words like because, since, so, therefore, or as a result. Example: It rained, so we stayed home.

In English, expressing purpose shows the reason for an action. It answers the question “why?”. You can use forms like to, in order to, so as to, or for with a noun. Example: “I study to learn.” It helps connect an action with its goal in a clear way.

In English, hypothetical structures talk about situations that are imagined, possible, or not real. They often use if with a verb, followed by a result. They are useful for speaking about hopes, advice, warnings, and events that happened differently or may happen later.

In English, logical connectors show how ideas are linked. They help you add information, show contrast, give a reason, or explain a result. Examples are and, but, because, so, and however. They make speaking and writing clearer, smoother, and better organized.

In English, modal markers show if something is possible, certain, allowed, or necessary. They often use words like can, must, may, might, and should. They help explain what the speaker thinks about an action or situation and how sure the speaker feels.

In English, defining relative clauses give necessary information about a person or thing. They help identify exactly who or what we mean. Non-defining relative clauses give extra information only. They are separated by commas and often use who, which, that, or whose.

In English, the passive is used when the focus is on the result of an action or on the person or thing that receives it, not on who does it. It is often formed with be and a past participle: The door is closed. The doer can be added with by.

In English, relative pronouns connect one part of a sentence to another. Words like who, which, that, whose, and where add more information about a person, thing, or place. They help you avoid repeating words and make your sentences clearer and more natural.

In English, reported speech is used to tell what someone said or thought without repeating their exact words. We often change the verb tense, pronouns, and words about time or place. It helps us report statements, questions, or thoughts in a clear and natural way.

In English, the subjunctive is used when we talk about things that are not simple facts. It can show a wish, a request, advice, importance, or doubt. It often comes after verbs like suggest, insist, or recommend, and uses the base form of the verb, for example: “I suggest he go.”
