Words / C1

in-FAL-uh-bl/ɪnˈfæləbl/

Infallible means never wrong, or never failing: an infallible test, no one is infallible. Exception (already in the dictionary) is what you log when the claim fails; reliable is milder. Foyer copy is not a hidden exception.

Meaning

Never wrong, or never failing.

Examples

• “No codebook is infallible; log the exception, do not hide it in the foyer copy.”
• “Unerring is the close twin. Reliable is milder. Copy is branding. An exception is a file. Write the exception; then print the copy if it still holds.”

Good to know

Never wrong or never failing. Milder: reliable. Foyer copy ≠ a hidden exception.

Near in meaning

unerring, unfailing, flawless
