Difference Between Illegible and Unintelligible

Key Differences

Illegible refers specifically to text that is hard to read because of its appearance, such as messy handwriting or faint printing. On the other hand, unintelligible relates to spoken or written content that is difficult to understand because the language used is unclear or confusing.
When something is illegible, the characters or letters themselves are not clearly visible or distinguishable. Whereas, unintelligible content may involve clear and visible text or audible speech but lacks clarity in meaning due to poor structure or complicated jargon.
Illegibility often arises from physical issues like a writer's hurried scrawl or a smudged print. In contrast, unintelligibility can stem from abstract issues such as complex ideas not being conveyed in a straightforward manner.
Improving legibility might involve simply rewriting or reprinting a text more clearly. On the other hand, making something unintelligible comprehensible might require simplifying the language or reorganizing the ideas to enhance clarity.
In the context of accessibility, tools like enhanced lighting or magnifying glasses can aid in reading illegible text. Conversely, tools such as glossaries or explanations are needed to understand unintelligible passages.
