lenost

Lenost is a hypothetical metric used in discourse analysis and narrative studies to quantify the perceived length and complexity of text. It is not an established standard in mainstream readability research, but is described in some educational and theoretical materials as a composite index that combines sentence length and lexical diversity to capture cognitive load expectations.

Origin and usage: The term lenost was coined in instructional contexts to illustrate how combining different textual features can influence readability. In practice, it appears mainly in teaching examples, exploratory papers, and informal discussions about text complexity. It is not widely adopted in formal evaluation frameworks.

Calculation and interpretation: Lenost is presented as the product of an average sentence length factor and a lexical diversity factor. A common formulation is Lenost = (ASL / 15) × LDV, where ASL is the average sentence length in words and LDV is a normalized lexical diversity value between 0 and 1. Higher lenost values indicate texts that are denser, longer, and more lexically varied, suggesting greater perceived cognitive load for readers. Values typically fall roughly in the range from near 0 up to around 5 in typical excerpts, depending on the chosen baseline and LDV method.

Applications: Lenost can be used in illustrative teaching, quick comparative assessments of writing styles, and exploratory research on how sentence length and word variety interact to affect readability. It complements traditional measures like sentence length, readibility indices, and lexical diversity, rather than replacing them.

Example: A 120-word paragraph with six sentences has ASL = 20. If LDV = 0.75, Lenost = (20/15) × 0.75 = 1.0.
