eye-OH-tuh

I learn an interesting word today:

iota \eye-OH-tuh\, noun:
1. The ninth letter of the Greek alphabet, corresponding to
the English i.
2. A very small quantity or degree; a jot; a bit.

Copernicus, Galileo and Kepler taught us that the Earth
moves and rotates while the heavens stand still, but this
did not change by one iota our direct perception that the
heavens do move and that the Earth does not budge.
-Julian Barbour, The End of Time

He has not moderated his demands one iota in seven years.
-Charles Krauthammer, "The Last Deal, or No Deal,"
Time, July 17, 2000

I couldn't help feeling that in spite of every iota of
evidence to the contrary, something was about to happen.
-Jane Smiley, The All-True Travels and Adventures of
Lidie Newton
