Basically - Receptive language is how you process the information you receive.
This is how you understand vocabulary (idioms, multiple meaning words, synonyms, antonyms, morpheme use), meaning, tone used in a message, and nonverbal language.
Do you understand the questions asked?
Do you understand directions regularly?
Do you have a difficult time understanding what is being read?
Do you need extra repetitions, not brought on by a hearing difficulty?
There is so much to under this area of understand and processing information. At this point what is on this page is just a small part of what is involved.
More information to come.
