retest

The word 'retest' is a modern English formation built from two Latin-derived elements. The prefix 're-,' meaning "again," is one of the most productive prefixes in English, attached to verbs to indicate repetition. The root 'test' originates from Latin testari ("to bear witness") and testum ("an earthen pot"), the latter being a tool used in ancient metallurgical assays, thus linking the concept of a container to one of examination and proof. The compound 'retest' logically follows this lineage, combining the idea of repetition with that of a trial or assessment, to specifically denote the action of examining something a second or further time.

Structure: re (again) + test (trial) - re: Latin origin, a prefix meaning "again" or "back." - test: Latin origin (from testum, an earthen pot used in assaying metals), functioning as a root meaning "trial" or "examination."
