In my experience working in boardrooms, drafting emails, and even engaging in casual chats, the phrase “thus far” has always stood out as a surprisingly refined choice in both formal writing and day-to-day conversations. I remember one meeting where a colleague used it mid-speech, and it made the entire tone of the message feel more intentional. That’s the kind of value this phrase brings—it’s not just about grammar, but about the context, the audience, and how you grasp its usage. It’s easy to wonder whether it’s correct when simpler alternatives like “so far” exist, but the short answer is absolutely. What makes the phrase strong is that its meaning has remained consistent for over a century, fitting naturally into books, literary works, and real-life settings.
The beauty of “thus far” is how it functions as a precise instrument in everyday communication. Its strength depends on when and why it’s used—sometimes to add weight, other times just to sound a bit more polished. But like anything, it can be misused if not understood. That’s why it helps to explore real examples, dive into the meaning, and take things step by step. Over time, I’ve come to find that it’s not just about swapping words—it’s about learning how a sentence hinges on clarity. This guide covers not just tips and references, but smart, practical ways to avoid common pitfalls. If you ever feel unsure, take a pause, reflect on the situation, and ask yourself what you want the reader to think or feel. A well-timed “thus far” can break the noise, steer a conversation, and help your words work exactly as intended.
What Does “Thus Far” Mean in American English?
Simply put, “thus far” means “up to this point in time” or “so far.” It’s a phrase that shows progress or something that has happened or been true until now.
The word “thus” means in this way or to this extent, and “far” refers to distance or progress. Put together, “thus far” tells us about how far something has come — not physically, but in terms of time, work done, or development.
For example:
- “Thus far, the project has gone smoothly.”
- “The experiment has yielded positive results thus far.”
This phrase tends to be more formal than “so far,” which you hear a lot in everyday speech.
Is “Thus Far” Grammatically Correct?
Yes, it is! “Thus far” is a perfectly correct adverbial phrase. It usually comes at the beginning or in the middle of a sentence to modify the verb or the whole sentence.
Correct examples:
- “Thus far, we have completed three phases.”
- “The plan has been successful thus far.”
Incorrect example (awkward usage):
- “The results are positive thus far.” (This is okay but less common than the previous examples.)
The phrase has been used correctly for centuries, even appearing in Shakespeare’s works, so it’s solid grammar.
When and How to Use “Thus Far”
You’ll mostly find “thus far” in formal writing and professional speech, such as:
- Academic papers: “Thus far, the data supports our hypothesis.”
- Business reports: “Thus far, sales have exceeded expectations.”
- Legal opinions: “The law has been effective thus far.”
- Scientific research: “No side effects have been observed thus far.”
Avoid using “thus far” in casual conversations because it sounds too stiff or formal. In daily chats, stick with “so far.”
“Thus Far” vs. “So Far”: What’s the Difference?
Both phrases mean almost the same thing — up to this point — but their tone and usage differ.

Tone | Formal, academic | Casual, conversational |
Common contexts | Legal, scientific, business | Everyday conversation, informal writing |
Frequency | Less common | Very common |
Example | “Thus far, the findings are conclusive.” | “So far, the trip has been great.” |
Use “thus far” when you want to sound formal or professional. Choose “so far” for casual talks or informal writing.
