People often get confused between “what” and “which” and wonder whether there’s a difference between “what” and “which”. People usually find difficulty in deciding which term to use depending on the circumstances. 

However, there’s not a huge difference between “what” and “which”, and they’re often interchangeable. In this article, I’ll tell you what is the difference between these two terms.

What Does “What” Mean?

What” is a word that a person uses to ask a question. The word “what” is a pronoun, where sometimes it acts as a determiner. The primary usage of the word “what” is to pose a question with unlimited data. When there’s more than one answer to a questions, an individual prefers to use this pronoun to pose.

The word “what” is used to question, or inquire about someone. “What” can be used as a subject, object, and complementary verb. People choose to use this pronoun to ask about the unknown and infinite things.

In the English language, this pronoun plays a significant role in questioning and inquiring. There are two types of questions that exist, with infinity options and with limited options. An individual prefers to use this pronoun when asking a question with infinity replies.

Here are some of the examples using the pronoun “what”:

  • What is your name?
  • What are you reading?
  • What would you like to eat?
  • What are the chapters you are planning to study for the exam?
  • What did you like the most about this city?
  • What day is your flight?

The sentences that use “what” end with a question mark that allows people to answer. Generally, the term “what” prefers to pose a question individually. An individual who would like to ask a question or inquire about something to a particular individual primarily uses the term “what”.

“What” is considered an interrogative pronoun that counters the question to others. The pronoun “what” can be used in a sentence like an offering, requesting, or suggesting, when the pronoun had added with some other related words. For example:

  • What about Saturday night for a dinner?
  • What about going on a beach this weekend?

Notice in the above examples that an individual is offering and asking at the same time. These questions are usually asked by a group of people and sometimes by individuals too.

Which” is a term that people generally use to ask a question. “Which” is an adjective, where sometimes it acts as determining term.

All the people from all around the world who speaks English use this adjective to question something with limited answers. Instead of using the term “what”, people use “which” when the question has a few options to choose from.

However, sometimes instead of using the term “which”, an individual use the word “that” in sentences where it relates to the things that an individual knew. Here are some examples of the adjective:

  • Which dress are you choosing for photos?
  • In which school are you planning to go?
  • Which flight are you going to take?
  • Which pair of shoes have you decided to wear to a party?

As you can observe in the above questions that these questions are being asked from the person. In this first question, an individual who decides on the dress for the photoshoot had limited options. So you can notice the questions using the adjective “which” have limited replies.

When an individual uses the term “which” as a question, the other will give the information about something within the multiples. A person can ask questions to a group of people by using this adjective.
