Ludwig's WRAP-UP

In summary, the phrase "a customer which" is grammatically correct but less preferred than "a customer who" when referring to people. While usable, especially in certain contexts, it's important to consider the audience and level of formality. According to Ludwig, the phrase is common in News & Media and Science, but less so in formal business settings. When writing, using "who" for people provides better clarity, even though Ludwig AI confirms that the phrase is perfectly usable. Alternatives include "a customer that" and "a client who", depending on the specific context and nuance you wish to convey.

FAQs

When should I use "a customer who" instead of "a customer which"?

When referring to a person, it's generally better to use "who" instead of "which". "Who" is a relative pronoun specifically used for people, while "which" is typically used for things. Therefore, "a customer who" is usually the more appropriate choice.

What are some alternative ways to phrase "a customer which"?

You could use phrases like "a client who", "a customer that", or "an individual who", depending on the context and desired level of formality.

Is "a customer which" grammatically incorrect?

While not strictly incorrect, using "which" to refer to a person is generally discouraged in favor of "who". Ludwig AI confirms that "a customer which" is usable, but it's important to consider the audience and context. In formal writing, "who" is almost always preferred.

Can I use "that" instead of "which" in the phrase "a customer which"?

Yes, "that" is often a suitable alternative. "A customer that" is grammatically correct and can be used in many contexts, especially in less formal writing. However, "who" remains the most appropriate choice when referring to a person.
