What is What?  

The What is a word that an individual uses to pose a question. The word What belongs to the Pronoun, where sometimes it acts as a determin. Some examples of the Pronouns are  

• What are the questions you are preparing for the test?  
• What do you like the most about me?  
• What day is your surgery?  

What had been called an interrogative pronoun counters the question to others. The Pronoun What can pose the sentences like an offering, requesting, or suggesting, when pronoun had added with some other related words. For example  

• What about Sunday morning for a walk?  
• What about going on vacation on holidays?   

The above questions say that an individual is offering and asking at the same time. These questions will be posed to a group of people and sometimes to individuals, too.  

What is Which?  

Which is the word that people use to pose a question. It is well known as an Adjective, where sometimes it acts as a determining term. Some of the examples on the Adjective are  

•  Which train are you taking to go?  
• Which pair of dresses do you decide to wear to a party?

2. What ends with a question mark where the term “Which” is sometimes incomplete sentences in paragraphs.
