Expert writing Tips

Best practice

When referring to a specific group or category, replace "that" with "of those" or a more specific noun to improve clarity and grammatical correctness. For example, use "how many of those" or "how many books" instead of "how many that".

Common error

Avoid using "that" vaguely. Ensure "that" has a clear antecedent. If you're referring to a specific set of items, specify it directly, e.g., "how many of the selected items" instead of relying on context.

Ludwig's WRAP-UP

In summary, "how many that" is a grammatically questionable phrase that aims to inquire about a quantity but lacks precision. Ludwig AI analysis suggests it is best replaced with more specific and grammatically sound alternatives like "how many of those" or "how many [specific items]". Its usage is rare and primarily found in informal contexts or news media, where clarity might sometimes be sacrificed for brevity. When writing professionally or academically, it is advisable to avoid this construction in favor of more explicit phrasing.

FAQs

How can I properly ask about the quantity of something?

Instead of saying "how many that", which is grammatically awkward, use phrases like "how many of those" or specify the item you're counting, such as "how many books".

What's a more formal way to inquire about a number?

Instead of the informal phrasing of "how many that", consider using more formal options such as "what is the quantity of those" or "what is the number of items being considered?"

Is "how many that" grammatically correct?

No, "how many that" is generally considered grammatically incorrect. A more appropriate phrasing would be "how many of those" or specifying the noun, like "how many people".

When can I use "that" after "how many"?

Using "that" directly after "how many" is usually incorrect. It's better to specify what you're counting or use "of those" to refer to something previously mentioned. For example: "How many books are there?" or "How many of those are new?".
