Pro Tip
Avoid confusion with 're-test'
While 'retest' is typically written as one word, 're-test' (hyphenated) may occasionally appear in formal contexts to emphasize the 'again' aspect. However, 'retest' is the standard spelling in most cases.
Gold Rule
Context matters
'Retest' implies a second attempt to confirm or verify, not merely to repeat without purpose. Ensure the context reflects a need for reassessment.
Word Origin
Formed by the prefix 're-' (meaning 'again') + 'test' (from Old French 'test' meaning 'cupel,' a vessel used in assaying metals). First recorded in the early 20th century.
Usage Notes
Used primarily in formal or technical contexts. Avoid using 'retest' to mean 'criticize again' or 'reprimand,' which is a common misuse.
