Diana, an ELL student, is giving a presentation on a topic she knows well but struggles to recall the word. The teacher suspects she might be dealing with?

• A. Semantic dementia
• B. Aphasia
• C. Dysnomia
• D. Dyslexia

Answer: (C)

What’s being tested is the ability to retrieve a specific word from memory while speaking, a process called lexical retrieval or naming. When someone knows the concept well but can’t recall the exact word to name it—that “tip of the tongue” moment—that’s a word-finding difficulty. The term that captures this problem is dysnomia (also called anomia). It reflects a retrieval issue from the mental lexicon rather than a loss of understanding or a broad language impairment.

Why this fits the scenario: Diana can talk knowledgeably about the topic, showing her concept knowledge and overall language use are intact. She simply can’t access the precise term during the presentation, which aligns with a naming retrieval problem.

Why the other possibilities don’t fit as well: Semantic dementia would involve a gradual loss of understanding of word meanings and concepts across many areas, not just trouble finding a single word in a live presentation. Aphasia refers to broader language disorders that affect fluency, comprehension, or grammar, not just the occasional missing word for a familiar topic. Dyslexia is a reading disorder, not a speaking or naming difficulty.
