Which word refers to 'legibility' in German?

The term that refers to 'legibility' in German is "Lesbarkeit." This word encapsulates the concept of being readable or clear in print or handwriting, emphasizing how well text can be distinguished and understood by readers. In the context of typography, Lesbarkeit is crucial as it directly impacts how effectively information is communicated through written words.

The other options do not relate to the concept of legibility: "Blei" translates to "lead," which does not pertain to readability; "Schicht" means "layer," which is unrelated to text clarity; and "Abgelaufen" translates to "expired" or "outdated," which does not intersect with the topic of legibility. Thus, "Lesbarkeit" stands out as the correct term specifically connected to the quality of text that allows for easy reading.
