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
