trep-i-da-tion / trĕp-ĭ-dā-shən
1. fear; a feeling of dread or anxiety
But the first lie in the series is the one you make with the greatest trepidation and the heaviest heart.
Michael Chabon, 1963 –
2. (archaic) a condition of involuntary trembling or palpitation
They pass the planets sev’n, and pass the fix’d,
And that crystalline sphere whose balance weighs
The trepidation talk’d, and that first-mov’d.
From “Paradise Lost” by John Milton, 1608 – 1674
