Arduous \Ar"du*ous\ (?; 135), a. [L. arduus steep, high; akin to
Ir. ard high, height.]
1. Steep and lofty, in a literal sense; hard to climb.
[1913 Webster]

Those arduous paths they trod. --Pope.
[1913 Webster]

2. Attended with great labor, like the ascending of
acclivities; difficult; laborious; as, an arduous
employment, task, or enterprise.
[1913 Webster]

Syn: Difficult; trying; laborious; painful; exhausting.

Usage: {Arduous}, {Hard}, {Difficult}. Hard is simpler,
blunter, and more general in sense than difficult; as,
a hard duty to perform, hard work, a hard task, one
which requires much bodily effort and perseverance to
do. Difficult commonly implies more skill and sagacity
than hard, as when there is disproportion between the
means and the end. A work may be hard but not
difficult. We call a thing arduous when it requires
strenuous and persevering exertion, like that of one
who is climbing a precipice; as, an arduous task, an
arduous duty. "It is often difficult to control our
feelings; it is still harder to subdue our will; but
it is an arduous undertaking to control the unruly and
contending will of others."
[1913 Webster]
