Explanation at your level:
You use knocks when someone hits a door. If you want to enter a room, you knock. If you do it three times, those are three knocks. It is a very useful word for daily life.
When you arrive at a friend's house, you might hear knocks at the door. You can say 'He knocks on the door' to describe the action. It is also used to talk about the sound of a bad engine in a car.
The word knocks functions as both a verb and a noun. As a verb, it describes the action of tapping on a surface. As a noun, it refers to the sound produced. It is often used in idioms like 'knock on wood' to express a desire for continued good luck.
Beyond the literal meaning, knocks can be used figuratively to describe setbacks or criticisms, such as 'taking some hard knocks' in life. It is important to distinguish between the polite social gesture of knocking and the mechanical 'knocks' that indicate engine failure.
In advanced usage, knocks can imply a sense of persistent challenge or even a metaphor for the 'knocks' of fate. Writers often use the term to evoke a sense of urgency or to describe the rhythmic, perhaps ominous, sound of someone trying to gain entry. Understanding the nuance between the physical act and the abstract 'hard knocks' of experience is key to mastery.
Etymologically, knocks represents a convergence of Germanic roots that have remained remarkably stable in form. In literary contexts, the word can serve as a device for tension, where the sound of knocks at a door signals a turning point in a narrative. Its usage spans from the mundane—a visitor at the door—to the profound, representing the inevitable challenges one faces throughout a lifetime. Mastery involves recognizing these shifts in register, from the colloquial 'knock it off' to the more somber 'the hard knocks of experience.'

When we talk about knocks, we are usually talking about the sound of someone asking to come inside. Whether you are at a friend's house or an office, you use your knuckles to create a sharp sound on the wood or glass.
Beyond the front door, knocks can describe the rhythmic sounds a car engine makes when it isn't running quite right. It is a very versatile word that connects the physical action of hitting something with the auditory result of that hit.
The word knocks comes from the Old English word cnocian, which meant to strike or beat. It has deep roots in Germanic languages, sharing a history with words like the Middle Dutch knocken.
Historically, it was used to describe any heavy blow, but over time, it became specifically associated with the polite way of announcing one's arrival at a door. It is a classic example of an onomatopoeic word, meaning the word itself sounds a bit like the action it describes!
You will most often hear knocks in phrases like 'loud knocks' or 'a series of knocks.' It is very common in everyday conversation when describing someone arriving at a home.
In a technical context, you might hear a mechanic mention 'engine knocks.' This is a more serious usage, as it suggests something is broken inside the vehicle. Always pay attention to the context to know if it is a friendly visit or a car problem!

The word knocks is the third-person singular of the verb 'knock' (e.g., 'He knocks on the door'). As a noun, it is the plural form (e.g., 'I heard three knocks').
