Language disorders (and delays) for elementary school children (ages 6-14) involve the receptive and expressive language abilities. Language disorders may be diagnosed as aphasia, fluency, apraxia, grammar (semantics, syntax), idioms, and pragmatics.

Receptive language disorders comprise a child's difficulty understanding and processing information. 

Expressive language disorders are demonstrated in a child's speech and can include difficulty with word formulation, limited vocabulary, inability to use proper language, or use of socially inappropriate language.
