Expert writing Tips
Best practice
Avoid using "approximately always" in your writing. Opt for clearer and more grammatically accepted alternatives like "almost always", "usually", or "generally" to convey a similar meaning.
Common error
The word "always" implies certainty, while "approximately" implies estimation. Combining them creates a logical contradiction. Ensure your wording reflects the intended level of precision.

Ludwig's WRAP-UP
In summary, the phrase "approximately always" is grammatically questionable and generally not recommended for use. As Ludwig highlights, the combination of "approximately" and "always" creates a contradiction. While the intention might be to express a high degree of consistency with a small margin of error, clearer and more accepted alternatives like "almost always", "usually", or "generally" are more effective. Usage is rare and spans various contexts, but primarily appears in scientific and general reference materials. It's best to avoid this phrase in formal writing and opt for more precise and grammatically sound options.

FAQs
Why is the phrase "approximately always" considered grammatically incorrect?
The phrase combines the concept of estimation ("approximately") with the concept of certainty ("always"), creating a contradiction. It's better to use phrases that accurately reflect the degree of certainty you intend to convey.
What are some alternatives to "approximately always"?
Depending on the context, you could use alternatives like "almost always", "usually", or "generally".
Is there a situation where "approximately always" would be appropriate?
In very informal contexts or when intentionally creating a humorous or paradoxical effect, you might use "approximately always." However, in most writing, it's best to avoid the phrase.
How can I improve the clarity of my writing when trying to express something that is 'almost' always true?
Be specific about the degree of certainty. Instead of "approximately always", quantify the exceptions. For example, "in 99% of cases" or "almost without exception" offer more precise communication.
