I know a seven letter word which we used very often.
Letter five six and seven increases every year.
Letter three and four are the same.
Letter three two and five covers about seventy percent of the world.
It can sizzle like bacon,
It is made from an egg,
It has plenty of backbone, but lack a good leg,
It peel layers like onions, but still remain whole,
It can be long, like a flagpole, yet fit in a hole.
I am eight letters long - "12345678" My 1234 is an atmospheric condition.
My 34567 supports a plant.
My 4567 is to appropriate.
My 45 is a friendly thank-you.
My 678 is a man's name.
Q: What word am I?
