Dyslexia refers to:

Correct definition: Dyslexia is a specific learning disorder that primarily affects accurate and/or fluent word recognition, decoding (phonological processing), and spelling. It does not mean a general inability to learn.

Why the given options are not accurate:

• “Inability to write” describes writing-specific problems (dysgraphia). Dyslexia mainly affects reading and spelling; writing can be affected but is not the core definition.

• “Inability to learn” is too broad and misleading. Dyslexia is a specific difficulty with reading-related skills, not a global incapacity to learn.

• “Inability to speak” refers to speech or language production disorders and is not the same as dyslexia.

• “Inability to see” describes vision impairment; dyslexia is unrelated to basic visual acuity.

Notes for instructors and students:

• A precise description to teach is: "Difficulty with reading, decoding, and spelling due to a specific learning disorder (dyslexia)."

• Common signs include slow or inaccurate word reading, difficulty decoding unfamiliar words, and poor spelling, despite normal intelligence and adequate instruction.
