Can I correct first your question? When can we use these (use these when u reffer to more than one object or anything) words? Sample sentences: whatever- I will accept whatever you will give me. Whoever- I will accept you whoever you are. Wherever- Wherever you are, don't forget to call me. Whenever- whenever there are calamities, the people in our place are helping each other. Pls correct me also if there's something wrong. Thanks
