WRU

WRU stands for "Word Reference Unit," which is a measurement used in linguistics and language processing to quantify the complexity or size of text or speech at the word level. It helps analyze language skills, vocabulary usage, or readability by considering the number of words and their contextual relevance. Essentially, WRU provides a standardized way to evaluate or compare language data, often used in educational assessments, linguistic research, or natural language processing applications to measure how much or how complex the language is in a given sample.
