Full Form of MLU
What is MLU?
Mean Length of Utterance (MLU) is a quantitative measure used in linguistics and child language development to assess the average length of a child's spoken utterances, typically in morphemes or words. It is a key indicator of grammatical and syntactic maturity, often applied in speech-language pathology, early childhood education, and developmental psychology. In India, MLU is used by speech therapists, special educators, and researchers to evaluate language acquisition in children, especially those with communication disorders or developmental delays. Assessments are conducted in both clinical and school settings, often in multilingual contexts where MLU can be adapted to Indian languages such as Hindi, Tamil, or Bengali. The metric helps track progress in language therapy and supports early intervention programs. For competitive exams like CTET, NET in Education, and rehabilitation courses, questions on MLU are common, focusing on its interpretation and application in language assessment. MLU provides a reliable, evidence-based foundation for understanding how children build linguistic structure over time.

How is MLU calculated?
MLU is calculated by dividing the total number of morphemes (or words) in a language sample by the total number of utterances, typically based on 50-100 consecutive utterances.
Why is MLU important in child development?
MLU helps identify language delays, monitor progress in speech therapy, and provides a normative benchmark for language acquisition in children up to about 5 years of age.
