Hello Friends ,😇 we have to learn English so 1st have to know meaning of words in Hindi. so start it into free. The “who” and “why” can be longer or shorter depending on the context. For example, if you’re speaking at a wedding, you’ll want to explain your relationship to the bride and groom and why they mean so much to you. But if you’re presenting to your class at school, you may be able to head straight into your thesis.
