1. arduous

   Arduous (Latin arduus, steep) signifies primarily so steep and lofty as to be difficult of ascent, and hence applies to that which involves great and sustained exertion and ordinarily for a lofty aim; great learning can only be won by arduous toil. Hard applies to anything that resists our endeavors as a scarcely penetrable mass resists our physical force. Anything is hard that involves tax and strain whether of the physical or mental powers. Difficult is not used of that which merely taxes physical force; a dead lift is called hard rather than difficult; breaking stone on the road would be called hard rather than difficult work; that is difficult which involves skill, sagacity, or address, with or without a considerable expenditure of physical force; a geometrical problem may be difficult to solve, a tangled skein to unravel; a mountain difficult to ascend. Hard may be active or passive; a thing may be hard to do or hard to bear. Arduous is always active. That which is laborious or toilsome simply requires the steady application of labor or toil till accomplished; toilsome is the stronger word. That which is onerous (Latin onus, a burden) is mentally burdensome or oppressive. Responsibility may be onerous even when it involves no special exertion.

How to use arduous in a sentence?

1. Socrates:

   Regard your good name as the richest jewel you can possibly be possessed of - for credit is like fire when once you have kindled it you may easily preserve it, but if you once extinguish it, you will find it an arduous task to rekindle it again. The way to gain a good reputation is to endeavor to be what you desire to appear.

2. Jessica Levinson:

   Trump thinks ‘our country is going to hell.’ Well, there is likely little more than a chance in hell that we are going to amend the Constitution, amending the Constitution is one of the most serious things that lawmakers can do. Therefore the path to doing it is rightfully arduous. I would put the chances … as beyond a longshot. To be sure, changing the Constitution, the supreme law of the land, would require a two-thirds vote in Congress, then ratification from three-fourths of state legislatures. It could also be changed through a constitutional convention in which at least 34 states convene to vote on an amendment, which would then need ratification from a minimum 38 states. Trump since announcing his candidacy in mid-June has made illegal immigrants from Mexico a top concern and has suggested several solutions -- including a wall along the southern border and the change to birthright citizenship.

3. Zeng Yixin:

   The epidemic situation is now fragmented domestically, but the task of preventing a rebound of the epidemic remains arduous, the epidemic situation abroad is still severe and complex, and the pressure to defend against the outside continues to increase.

4. Serena Williams:

   This is only my second serious tournament back, i worked really, really hard (to get back playing) and it's been a long, arduous road but I always expected to come out and do the best I can do.

5. Jim Ritterbusch:

   Predicting short-term price swings has become extremely difficult given the arduous process of predicting the impact of the Delta variant on forward global oil demand, particularly in countries such as China where data is much less transparent than that of the U.S..
