unsure

I remember trying to cast him in a movie a year before Taken, and they were unsure about him.

We are unsure of the inward way, and our available resources are not yet adequate to this type of exploration.

They were unsure of being seen by the floating grey of eyes patient to gaze from their vast distance.

And he rose with unsure joints and offered to lead the way to the wine cellar.

I cry thee mercy not to have told thee, but seeing how unsure it were, I thought it more kindlier not to trouble thee.

Then she turned and waited for me, who came very deliberately, feeling the unsure contact of sole and wax.
