When you’re writing or speaking, it’s easy to fall into the trap of overusing phrases that seem interchangeable, but when it comes to “thus far” and “so far,” the two phrases aren’t quite the same.
Understanding their nuances can elevate your communication skills and help you choose the right phrase based on context. Though both refer to something that has happened up to the present moment, their tone, formality, and context of use differ.
In this comprehensive guide, we’ll explore the key differences, ideal usage, and provide examples that will help you confidently use “thus far” and “so far” in your writing and conversations.
What Does “Thus Far” Mean?
Definition and Usage
“Thus far” refers to something that has happened or progressed up to the present moment. It’s often used in formal or professional contexts where a sense of authority, thoroughness, or precision is required. This phrase tends to convey a more serious tone, making it suitable for academic papers, business reports, speeches, and other formal writing.
The phrase gives a sense of finality, implying that what has occurred so far is part of a larger process or project. It suggests that there may be more to come, but focuses on what has already been achieved or understood.
Tone and Context
“Thus far” is often associated with situations where things are still ongoing but have made notable progress. It’s a way of acknowledging the work that’s been done while maintaining an air of formality. The tone is more measured, deliberate, and polished, making it appropriate for high-level professional or academic discourse.
Examples
- Business Email: Thus far, the project has met all its deadlines and exceeded our expectations.
- Scientific Research Paper: Thus far, the data suggests a positive correlation between the variables.
When to Use “Thus Far”
- Formal contexts: “Thus far” is ideal for business communication, academic papers, scientific research, and speeches. It adds a sense of professionalism and can be seen as more intellectual.
- For serious or detailed reporting: When you need to be precise and formal in your communication, this is the perfect phrase to use.
What Does “So Far” Mean?
Definition and Usage
“So far” is the more casual and commonly used phrase. It has the same meaning as “thus far,” referring to something that has happened up until the present moment. However, “so far” is less formal and fits better in everyday conversation and informal writing.
The phrase conveys progress or results to date but doesn’t carry the same heavy, authoritative tone as “thus far.” It’s ideal for casual situations, such as chatting with friends, writing blogs, or giving a relaxed update.
Tone and Context
“So far” is widely used in informal contexts, where the conversation or writing is relaxed. It can reflect progress that’s been made, but it implies that there’s more to come, making it a bit more open-ended and less definitive than “thus far.” It’s the go-to phrase for blogs, social media, and emails to friends or colleagues.
Examples
- Blog Post: So far, I’ve only tried the first two chapters of this book, but it’s been amazing!
- Casual Conversation: So far, we’ve raised $3,000 for the charity event!
When to Use “So Far”
- Informal contexts: Use “so far” in personal communication, casual conversations, blog posts, and social media.
- For relaxed or ongoing updates: If you’re giving an update or reflecting on progress but want to maintain a conversational tone, “so far” is the perfect choice.
Key Differences Between “Thus Far” and “So Far”
While “thus far” and “so far” are often used to describe progress up to the present moment, their primary difference lies in their tone, formality, and the context in which they are used. Let’s break it down further:
Aspect | Thus Far | So Far |
Formality | More formal, used in professional, academic, and technical settings | Informal, used in casual and everyday contexts |
Tone | Serious, polished, authoritative | Relaxed, conversational |
Usage Context | Business reports, scientific papers, speeches, formal communication | Blog posts, emails, social media, casual conversations |
Implication | Suggests a thorough or completed task/project | Implies progress, but open to future development |
Example | The research findings, thus far, have been positive. | So far, I’ve completed half the book. |
Are “Thus Far” and “So Far” Interchangeable?
The answer is yes and no. In some situations, they can be used interchangeably because both refer to progress up to the present. However, there are key differences that affect their appropriateness based on context.
- Interchangeable Contexts: When you’re talking about progress or results, both phrases can work, but they will convey different tones.
- Formal context: “Thus far, we have achieved our milestones.”
- Casual context: “So far, we’ve had a good time on this trip.”
- Formal context: “Thus far, we have achieved our milestones.”
- Non-Interchangeable Contexts: While “so far” can often be substituted for “thus far” in casual contexts, using “thus far” in an informal conversation can sound stiff, while “so far” in a formal context will make your writing sound too casual.

When to Avoid Using “Thus Far” and “So Far”
Both phrases can become repetitive if overused. Here are some alternatives to keep your writing fresh and varied:

- Example: “Up until now, we’ve had a smooth process.”

Using these alternatives can prevent overuse of “thus far” and “so far” and keep your writing from feeling repetitive.
