Word learning is a research area that focuses on how individuals acquire and comprehend new words in their native language or in a second language. This area of study examines the cognitive processes involved in storing, retrieving, and using words in various contexts, as well as how individuals develop their vocabulary over time. Researchers in this field investigate factors such as phonological, semantic, and syntactic cues that contribute to word learning, as well as the role of context, feedback, and individual differences in the acquisition and retention of new vocabulary. Additionally, word learning research also explores the implications of word learning difficulties or delays for language development and academic achievement.
