What is the meaning of identifical?

"Identifical" is not a real word in the English language. It's likely a misspelling of identical.

Identical means exactly the same, with no differences at all. For example:

* "The twins are identical, it's hard to tell them apart."

* "The two paintings are identical, except for the color of the sky."

If you meant to use "identifical," you should replace it with "identical" to make your sentence grammatically correct and clear.
