Phonology:  the study of the sound system of language.  The phonological system governs the ways in which sounds in a language can be combined to form words.

Phonological Disorder

A phonological disorder is a language disorder that affects the ability to organize speech sounds into a system of sound contracts.

Commonly, children with a phonological disorder may have:

• problems with words that begin with two consonants such as “spoon” becomes “poon.”
• problems with words that have a certain sound.  The child may either delete these sounds, not pronounce them clearly or use a different sound in their place such as “bi” for “bike,” “wope” for “rope” and “nana” for “banana.”
