The retardment of the project schedule caused a cascade of missed deadlines.

The project suffered multiple retardments due to unexpected supply shortages, pushing back the completion date by months.

The committee acted retardively, imposing extra paperwork that slowed the implementation of the project.

In older medical textbooks, retardism was used to describe what is now called intellectual disability.

During the high-speed trials, engineers observed unexpected retardings that affected the system's performance.

In the 19th-century medical record, the term retardate was used to describe patients with intellectual disabilities, but today it is considered offensive.

The chemists analyzed several retardates produced during the synthesis to determine their structural differences.

The retardive polymer lining extended the service life of the tank by slowing corrosion.

The retardative polymer layer slowed the release of volatile compounds during heating.

The instrument measured several retardances across the sample, revealing unexpected anisotropy.
