During a language evaluation, substitutions such as 'tar' for 'car' and 'comb' for 'brush' illustrate which type of errors?

• A. Neologisms
• B. Circumlocutions
• C. Phonemic and semantic paraphasias
• D. Groping behaviors

Answer: (C)

Substitution errors in naming point to disruptions in how the brain retrieves and encodes words. Saying “tar” for “car” shows a phonemic paraphasia—the speaker produces a real word that sounds similar to the target, indicating a mismatch at the sound level. Saying “comb” for “brush” shows a semantic paraphasia—the substitute is related in meaning to the intended item, reflecting a mix-up at the concept or category level. When both types appear, it’s a mixed paraphasia pattern, common in certain language disorders like aphasia. This differs from neologisms (made-up words), circumlocutions (describing around the word), or groping behaviors (difficulty initiating speech without a substitute).
