WHO has a possessive whose and an objective whom.
WHICH and WHAT are not inflected.
WHO may be either masculine or feminine.
WHICH and WHAT may be of any gender.
The objective WHOM often begins a question. Care should be taken not to write who for whom.
WHICH and WHAT are used as interrogative adjectives.

2. What village is this?
The interrogative adjective what may be used in a peculiar form of exclamatory sentence. Thus….
1. What a cold night this is!
2. What courage he must have had!
WHAT! by itself often serves as an exclamation such as…..What! do you really think so?
In this use WHAT may be regarded as an interjection.
