He is twenty years older to me? Is it right sentence? Or otherwise, sometimes we may say- My son John is two years elder than my daughter. True? No.
I am not referring the facts, rather I am referring the structure.
We need to remember older than is the correct form- e.g – She is older than all her friends. Usually, among siblings we generally use elder. For example- My son John is two years elder to my daughter.
So remember the point- Older than / Elder to.
Moreover, you need to remember- we refer someone as elder e.g Elder brother. Not older brother.
In addition to that we always say- we need to respect elders. Mind it -not olders.
Elder is descended from the old English word ELDRA , which refers to a parent or other older person.
