Also known as the listening vocabulary, it contains the productive, or expressive vocabulary. Receptive Language Disorder - Receptive language disorder is a type of learning disability affecting the ability to understand spoken, and sometimes written, language. Students with receptive language disorders often have difficulty with speech and organizing their thoughts, which creates problems in communicating verbally with others and in organizing their thoughts on paper.
Lexical- Lexicalwords- 1. Of or relating nouns referring to to the vocabulary, things words, or morphemes of a language. 2. Of or relating to lexicography or a lexicon.
