Alone

The doctor alone could determine the cause of the illness.

The house alone was worth millions of dollars.

She was the only one who completed the task alone.

She dreaded the idea of spending the holidays alone.

The empty classroom made her feel alone and forgotten.

The abandoned building stood alone on the outskirts of town.

The singer's voice alone was enough to move the audience to tears.

The hiker got lost and had to spend the night alone in the woods.

She was the only one alone at the party, while everyone else was dancing.

She needed some alone to clear her mind before making the decision.
