In this lesson, you will learn question words in more detail 

to have a greater understanding of when and how they are used.

In the English language, there are “Yes/No” questions and “Wh-” questions.

Question words are also called “wh-” questions because these words include the letters ‘W’ and ‘H’.

Wh- questions start with whatwhenwherewhowhomwhichwhosewhy
