‘Why,’ on the other hand, is used to inquire about something, or to ask for an explanation about a situation. It is mainly used to seek the reason, cause, or purpose for something. It is more of an authoritative question. It demands an answer, as to ‘why did this happen?’ or ‘why did you or didn’t you do this.’ For example: Why is she at the party? (I want to know the reason.)
As ‘why’ is a standard form of a question, it is used in a standard question form, which means that the subject and verb are inverted. In a question format, the subject follows the verb, such as ‘Why did you say that?’ as opposed to a regular sentence format which is subject verb object, e.g. ‘You did say that.’ This is also the case for how but only when it is being used as a question. In a sentence, the format would still the traditional ‘subject – verb – object’.
