Dr. Hards reviewed the patient's records before the morning rounds.

The weaver separated the hards from the flax to prepare them for spinning.

We faced several hards during the project, but learned from each setback.

The old inn stood hard by the river, its windows glowing with lamplight.

I saw the team hard at it, finalizing the project before the deadline.

The Vickers hardnesses reported in the study varied significantly between the heat-treated and annealed samples.

Laboratories across the country reported varying water hardnesses, which affected the performance of the newly installed filtration systems.

The laboratory compared the total hardnesses of samples collected from five different wells to determine treatment needs.

Please bring a hard copy of your presentation to the meeting in case the projector fails.

My grandmother, who is hard of hearing, prefers written notes during visits.
