vestige - vocabulary

noun

A visible trace, mark, or impression, of something absent, lost, or gone; a surviving evidence of a condition or practice.

Most people with whom I talk, men and women even of some originality and genius, have their scheme of the universe all cut and dried,—very dry, I assure you, to hear, dry enough to burn, dry-rotted and powder-post, methinks,—which they set up between you and them in the shortest intercourse; an ancient and tottering frame with all its boards blown off. They do not walk without their bed. Some, to me, seemingly very unimportant and unsubstantial things and relations are for them everlastingly settled,—as Father, Son, and Holy Ghost, and the like. These are like the everlasting hills to them. But in all my wanderings I never came across the least vestige of authority for these things. They have not left so distinct a trace as the delicate flower of a remote geological period on the coal in my grate.

—Henry David Thoreau Walden (1864)
