tyro \TY-roh\, noun:
A beginner in learning; a novice.

medical procedures or economic theory.
--Philip Zaleski, "God Help the Spiritual Writer," New
York Times, January 10, 1999
He was a sensitive, fine soul alert to the pleasures of
being green, a tyro, an amateur, unwilling to close his
mind before it had been tempted.
--Paul West, Sporting With Amaryllis
And, though we were mere tyros, beginners, utterly
insignificant, he was invariably as kind and considerate
and thoughtful, and as lavish in the gift of his time, as
though he had nothing else to do.
--Leonard Warren, Joseph Leidy: The Last Man Who Knew
Tyro is from Latin tiro, "a young soldier, a recruit," hence
"a beginner, a learner."
