through and through

[vil]

Dear teachers,

Would you be kind enough to give me your considered opinion concerning the interpretation of the expression in bold in the following sentences?

..I know you through and through by your likeness to your father… (B. Shaw, “ Mrs. Warran’s profession”)

Look, Vicki, you know me through and through. (M. Wilson, “My Brother, My Enemy”)

Oh, he was ordinary, through and through. (S. Lewis, “Selected Short Story”)

through and through = from beginning to end, entirely, completely, thoroughly, to the full, in all respects

V.

Your interpretation is correct.
