Now means at the present time or moment (adverb); immediately, without delay (adverb); or because of the fact that something has happened (conjunction). As a noun it refers to the present moment: for now, living in the now.
What Does Now Mean?
Now descends from Old English nu, sharing roots with Latin nunc, Greek nun, and Old Norse nu — all meaning "at this time". It is among the oldest and most stable words in the Germanic language family, unchanged in core meaning for over a thousand years. Its brevity and frequency make it one of the first words learners encounter, yet its full range of uses stretches well into advanced levels.
As an adverb, now can indicate the present moment ("What are you doing now?"), signal an immediate action ("Stop that now!"), or introduce a change in topic or narrative ("Now, let me explain something"). As a conjunction (typically now that), it introduces a reason based on a new or changed situation: "Now that you have read the instructions, try the exercise." As a noun it appears in fixed expressions such as for now, by now, and the philosophical phrase living in the now.
Mastering the different uses of now — especially the conjunction now that — is a key step towards natural-sounding English at B2 level and above.

Usage Notes
Three Core Uses to Master
1. Adverb of time (present): Now places an action at the current moment. It typically comes at the end of a sentence or clause: "What are you reading now?" or at the start for emphasis: "Now I understand."
2. Adverb of immediacy: When now means "immediately", it often carries a tone of urgency or authority: "Come here now!" In formal writing, immediately or at once are preferred alternatives.
3. Conjunction (now that): Now that introduces a subordinate clause expressing a cause rooted in a recent change. The main clause states the consequence. Either clause can come first: "Now that the results are in, we can plan next steps" = "We can plan next steps now that the results are in." In very informal speech, that is sometimes dropped: "Now you mention it, I agree."
Discourse marker: In speech and informal writing, now also functions as a discourse marker to signal a shift in topic, give instructions, or soften a request: "Now, let me show you how this works." This use does not carry a time meaning and is often unstressed.
Common Mistakes
Watch Out For
Now that I finished the course, I feel more confident.
Now that I have finished the course, I feel more confident. (Use present perfect after now that to show a recently completed action.)
I live in the now moment.
I live in the now. (As a noun, now does not need an additional noun after it.)
Now, I am working here since three years.
I have been working here for three years now. (Now as a time adverb pairs naturally with the present perfect continuous; avoid mixing it with simple present + since/for.)
Etymology
Now comes from Old English nu, a word found in virtually every Indo-European language: Latin nunc, Greek nun (νῦν), Sanskrit nu, and Old Norse nu. The word has remained almost completely unchanged in form and meaning for over 1,500 years of recorded English, making it one of the most ancient and stable items in the language. Its short, easily pronounced form and high communicative load ensure it will remain central to English indefinitely.
