Choose the correct one-word substitution for:
"Impossible to describe in words."
Show answer & explanation
Correct answer: B
Explanation
Correct Answer
Ineffable
Explanation
The question asks to find the single word that perfectly substitutes the given phrase. To solve vocabulary-based substitution questions quickly, break down the root words and prefixes of each option.
The prefix "in-" means "not" in all four options. Let's look at the roots:
Ineffable comes from the Latin root effabilis, which means "utterable" or "speakable" (from effari, meaning to speak out). Therefore, "ineffable" literally translates to "not able to be spoken or expressed in words." This perfectly matches the definition of something so grand, beautiful, or overwhelming that words cannot describe it.
Indelible comes from the root deleveren (to delete or erase). It means making a mark that is impossible to remove, wash away, or erase, such as indelible ink.
Infallible comes from the root fallere* (to deceive or fail). It describes someone or something that is completely incapable of making mistakes or failing, like an infallible plan.
Inaudible comes from the root audire (to hear). It means a sound that is impossible to hear.
Because "Ineffable" is the only word connected directly to speech and expression, Option 2 is the correct choice.
Key Points
One-word substitutions dealing with restrictions or impossibilities often rely on the negative prefix "in-". Identifying the core Latin root (like "aud" for hearing or "eff" for speaking) points directly to the correct definition.
The word "ineffable" is most frequently used in literature to describe extreme emotional states, divine experiences, or breathtaking natural beauty.
