When you write or speak in English, certain phrases can make your message sound more formal, precise, or polished. One such phrase is “thus far”.
You may have wondered whether it’s correct to use, when it fits naturally, and how it differs from phrases like “so far” or “this far.”
This guide will answer all your questions with clear examples, grammar explanations, and practical usage tips.
What “Thus Far” Really Means
At its core, “thus far” means “up to this point” or “up to now.” It communicates progress or extent, whether in time, quantity, or achievement.
For example:
- The team has performed well thus far, but challenges remain.
- Sales have increased thus far this quarter, exceeding expectations.
Notice how it emphasizes progress up to the present moment, rather than the future.
Key takeaway: “Thus far” is formal, precise, and often used in professional or academic contexts.
Breaking Down the Words
Understanding the individual words can clarify why this phrase works the way it does.
| Word | Meaning |
|---|---|
| Thus | Therefore, as a result, or up to this point (formal tone) |
| Far | Extent, distance, or degree (literal or figurative) |
When combined, “thus far” implies “to this extent up to now”. Unlike “this far,” which often refers to physical distance, “thus far” focuses on progress, achievement, or time elapsed.
Grammar Behind “Thus Far”
“Thus far” functions as an adverbial phrase, modifying verbs, clauses, or sentences. Its placement can vary:
- At the beginning of a sentence:
Thus far, the experiment has yielded promising results. - Mid-sentence:
The project has, thus far, exceeded all expectations. - At the end of a sentence (less common but correct):
We have met our targets thus far.
Rule of thumb: Use commas when “thus far” interrupts the flow in mid-sentence to improve readability.
Correct vs. Incorrect Usage
Even native speakers sometimes misuse “thus far.” Here’s how to avoid mistakes:
Incorrect:
- I have seen him thus far yesterday. (Tense mismatch)
- Thus far, I will finish my work tomorrow. (Temporal inconsistency)
Correct:
- Thus far, the research indicates a positive trend.
- The company has, thus far, implemented all recommended changes.
Tip: Always ensure present perfect tense works with “thus far,” because it emphasizes progress up to now.
