Homophones are words that sound the same but have different meanings, spellings, or both. The words "right" and "write" are a familiar example. A listener hears the same sound, but a writer must choose the spelling that matches the intended meaning.

Transition words help readers and listeners understand how one idea connects to the next. A sentence may be grammatically correct without a transition, yet the relationship between its ideas can still feel unclear. The right transition can show addition, contrast, cause, sequence, emphasis, or conclusion in only a few words.

Passive voice is a useful English structure that shifts attention from the person doing an action to the action or its receiver. In "The email was sent yesterday," the email is more important than the sender. The sentence may not even need to identify who sent it.

Conjunctions are small words with a big job. They connect words, phrases, and clauses so that a listener can understand how ideas relate. Without conjunctions, English can sound abrupt: "I studied. I was tired. I finished the assignment." With conjunctions, the relationship becomes clear: "Although I was tired, I studied, and I finished the assignment."

Reported speech lets you communicate what another person said without repeating every word exactly. Direct speech gives the original words: "I am tired." Reported speech gives the message from a new point of view: "She said that she was tired."

Articles in English are only a few letters long, but they carry important information. The words "a," "an," and "the" tell a listener whether a noun is general or specific, new or already known. English also uses the zero article, which means that no article appears before a noun.

Relative clauses add information about a noun inside one sentence. Instead of saying "I met a student. The student speaks three languages," you can say "I met a student who speaks three languages." The words "who speaks three languages" identify or describe the student.

Verb tenses show when an action happens and how the speaker views that action. English verb tenses can express a habit, an action in progress, a completed event, or a connection between two times. That is why simply memorizing "past, present, and future" is not enough.
