An expressive language disorder means you have trouble using content, form, or use of language when trying to convey a message. Speech is the actual sound of spoken language. Articulation is making sounds. Children who have articulation problems will probably substitute, leave out, or distort normal speech sounds at inappropriate ages. These errors should not, however, be present in the speech of a child over 5.
Phonology is the sound system of a language and the rules of sound sequences that make up words.
A phonological disorder is failing to grow out of patterns such as babbling or developing inappropriate sound patterns. Fluency disorders are problems with rate and rhythm of the flow of speech, such as stuttering and stammering.
