now

The word now mainly means the present time, the moment that is happening at this point. It is one of the most common ways to talk about what is happening in the present: "I can't talk now," "We are leaving now," or "She lives in Madrid now."

It often adds a sense of immediacy. In "Do it now" or "You need to stop now," the meaning is not just "at the present time" but also "without waiting." Because of that, it is very common in commands, warnings, and urgent requests.

Now is also used when we compare the present with the past: "I was shy before, but now I feel more confident." In sentences like "Now that you are here, we can begin," it connects a present situation to what happens next. It can also appear in questions such as "What now?" where it means "what should happen next?"

Another common use is in speech and writing to move the listener to a new point: "Now, let me explain," or "Now, about your question." In repeated forms like "Now, now," it can sound calming, warning, or gently correcting, depending on the tone.

So this is a small word with several jobs. It can point to the present, push for immediate action, compare one time with another, or guide the flow of a conversation.
