They're not equal. They are completely different in uses and meaning. "Ever" is related with "never." I'll never do it = I'll not do it ever. Why ever did you come here? Have you ever heard of him? Never = negative ever

Say is used while one isn't communicating with somebody else. Say to (=tell) is used while one is talking to somebody else. Talk to is used while the work is in a running process They say you can't do it, which is wrong. He said to (=told) me he'd try. I'll talk to him.

names of feelings, subjects, objects, persons, goups, animals, plants and everything is called nouns. simply, name of something is called a noun. as example, Mark, Catherine, Rose, Universe, Army, Committee, anger, sadness, Human, Lion, Bird, Water Lily, road, drug etc.

"has" is only used in third person singular number. As example, He/She/Mark/It/New York... has become famous. "have" is used all other times. As example, I/We/You/They/People/Mark And Robin/He and She/Mangoes... have become famous.

Happy belated birthday is correct.

Has been (for third person singular number) / Have been (for other than that condition):- 1. as present perfect tense- I have been there. 2. as passive sense- The situation has been handled. 3. as present perfect continuous tense- It's been raining since morning.

wh + 'be' verb + subject +extension who am I?

A real thinker is you.
