What is Backing?
Backing is a phonological process not present in typical development and an indication of phonological disorder if seen in more than 10% of the child’s words. Backing occurs when a consonant sound made in the front of the mouth (alveolars) is replaced by a sound made in the back of the mouth (palatal or velar). This process occurs when there are no velar or palatal sounds in the word already.
Examples:
toe = koe
doll = goll
drip = grick
light = yike
soap = shoap
