Expert writing Tips
Best practice
Use "or so" after a numerical value or quantity to indicate an approximation. This is particularly useful when the exact amount is unknown or unimportant.
Common error
Avoid placing "or so" at the beginning of a sentence. It typically follows the quantity it modifies. For instance, instead of saying "Or so, about 20 people attended", say "About 20 people, or so, attended".

Ludwig's WRAP-UP
In summary, the phrase "or so" is a versatile tool for indicating approximation or estimation in both written and spoken English. As noted by Ludwig AI, its grammatical function is that of an approximator, typically following a numerical value to soften the precision of the statement. It maintains a neutral register, making it suitable for various contexts, though primarily found in scientific texts according to the examples provided by Ludwig. For clarity, "or so" should be placed directly after the quantity it modifies to avoid misinterpretation. Alternatives such as "approximately", "roughly", and "about" can be used to achieve similar effects, tailoring the nuance to fit the specific context.

Alternatives include "approximately", "roughly", or "about", depending on the context and the degree of precision you want to convey.
Is it correct to say "or so" at the beginning of a sentence?
While grammatically not incorrect, it is less common and can sound awkward. It's better to place "or so" after the quantity you are approximating, such as "There were twenty people, "or so"".
How does the meaning of "or so" differ from "exactly"?
"Or so" indicates an approximate value, whereas "exactly" specifies a precise value. They are opposites in meaning; use "or so" when precision isn't necessary or possible.
