Do you realize that we are repeating the last word like an echo. This needless repetition of an idea in a different word or phrase or sentence is known as pleonasm . It is also known as redundancy or tautology.

Ponder over expressions as

climb up

ice cold

completely blind

freezing cold

handwritten manuscript

invited guests

pre planning

refer back

This is due to the influence of foreign languages on English . It is used deliberately for emphasis or from lack of realization that the words are redundant.

Does it not look like the opposite of oxymoron.
