syn: See honor.



(See also CANDIDNESS.)

in one’s heart of heart In the deepest, innermost recesses of one’s heart; in one’s most private and pure thoughts or feelings. The first heart in this expression means ‘core’ and the second heart means ‘seat of feeling, understanding, and thought.’ Although the corrupted heart of hearts is frequently heard, the original expression as it appeared in Hamlet is heart of heart.

Give me that man
That is not passion’s slave, and I will wear him
In my heart’s core—aye, in my heart of heart,
As I do thee. (III, ii)

Today this expression is used to assure the veracity or sincerity of any statement of belief.

In his heart of heart Froude would have admitted that. (Quarterly Review, October, 1895)
