Problems in the development of language can occur at a number of levels and in a number of ways. One can have difficulty with input or with output. Input problems, or what are called receptive language problems, can affect both what you take in and what you are able to put out, because what you put out is dependent on what you were able to take in. Output problems, or what are called expressive language problems, can affect what you are able to write or speak as well as what you are able to conceptualize within your brain.
