DIFFICULT
Arduous Hard
It is a hard school
With drawbacks of its own
A fight against great odds
A hard nut to crack
I had a pretty stiff time
He had to face an arduous task
Hard work ahead and plenty of it
Ay, there’s the rub.
Hamlet, III., 1
Not easy of accomplishment
Hard facts against which we chafe and fret
Not an easy task
It is easy to preach to the converted
It was rather a trying ordeal
The goal is far more remote than we had supposed it to be
It is difficult enough under the most favorable circumstances
It is difficult to possess one’s soul in patience when——
The situation was very badly complicated by——
He is up against a tough proposition
The way is not wholly smooth
It may seem a hard doctrine to preach at such a moment
We live in no soft and easy days
I find the medicine worse than the malady
As tangled as a hank of yarn that runs into knots continually
Processes which defy analysis
A great inertia which must be overcome
