When learning English, it’s easy to overlook how tiny expressions or phrases can reveal big differences in style. “Thus Far vs So Far“ both speak to progress and extent, but they differ in tone and formality. During my early days of writing professionally, I would use “thus far” while drafting a formal report – the structure just made sense. In contrast, while in a quick chat with colleagues, “so far” flowed naturally. This kind of usage made me realize how crucial understanding these subtle shifts is. It really sharpened my writing and speaking skills over time.
Being able to communicate with precision in various contexts starts with picking the right phrase. This article serves as a hands-on guide, showing what truly distinguishes the two. Their historical roots also matter – “thus” is often found in more structured academic texts, while “so” comes off as more modern and flexible. Knowing when to use each, and applying them through practical examples, helps you sound more natural and fluent. Whether you’re chatting casually or sticking to a formal script, this small tweak can make your message feel just right – and effortlessly so.
Understanding “Thus Far” and “So Far”
At their core, both thus far and so far mean “up to this point in time.” However, their usage differs in formality and style. Thus far tends to appear in more formal, academic, or official contexts, while so far fits naturally into casual conversation and informal writing.
For example, in a business report, you might read:
“Thus far, the project has met all key milestones.”
In contrast, in everyday talk, you’d likely hear:
“So far, the movie has been really good.”
Both convey progress but carry different tones.
The Historical and Etymological Roots of “Thus” and “So”
The phrase “thus far” derives from the word “thus,” which has Latin origins (from talis meaning “such” or “so”). Historically, thus was widely used in Middle English and earlier texts to indicate manner or degree and has retained a formal and somewhat archaic tone.
On the other hand, “so” has Old English roots, coming from the word swa, meaning “in this way” or “to this extent.” Over centuries, so has evolved into a versatile, informal, and commonly used term in everyday English.
This historical background helps explain why thus far feels formal and traditional, while so far sounds modern and conversational.
Formality and Context: When to Use “Thus Far”
Thus far is best suited for formal settings. It appears frequently in academic papers, legal documents, formal speeches, and official reports.
Situations ideal for “thus far” include:
- Research papers summarizing findings
- Legal statements outlining progress or limitations
- Formal business communications
- Official announcements
Here’s a formal example from a scientific article:
“Thus far, the study confirms the hypothesis under controlled conditions.”
Using thus far in casual settings can sound stiff or outdated, so reserve it for professional or serious contexts.
Versatility and Casualness: When to Use “So Far”
So far is the flexible, informal choice perfect for everyday speech and writing.
You’ll hear it often in:
- Friendly conversations
- Casual emails or texts
- Blogs and social media posts
- Informal presentations
For example:
“So far, I’ve really enjoyed the new restaurant.”
This phrase helps keep communication light, accessible, and natural. Its versatility makes it a safe default for most non-formal situations.
