<p>Okay. So you'll often come across a list of commonly confused diction errors on the internet and in many test prep books, but which ones, if any, actually appear on the real tests? </p>
<p>Here is a list of actual diction errors I've encountered ON THE REAL TEST. If anyone can add any that they have seen ON REAL TESTS, not ones in fake practice tests, please share.</p>
<p>PROSPECTIVE/PERSPECTIVE
CORROBORATE/COLLABORATE
IMMINENT/EMINENT
AUDIBLE/AUDITORY
DESIROUS/DESIRABLE</p>
<p>POPULOUS/POPULATED (THIS IS NOT NECESSARILY A DICTION ERROR..BUT I'VE SEEN AN ACTUAL TEST QUESTION..WHERE IT SAID SOMETHING LIKE "MOST POPULOUS REGION ..AND EVERYONE THOUGHT IT SHOULD BE POPULATED REGION BUT POPULOUS WAS INFACT CORRECT)</p>
