What is cluster reduction? Provide an example.

• A. Omission of a consonant in a cluster; e.g., a child may say "blue" as "boo" or "play" as "payer" (dropping the /l/ or /j/).
• B. Insertion of a vowel to break up a consonant cluster.
• C. Omission of a sound in fluent speech.
• D. A change of a consonant to become a vowel.

Answer: (A)

Cluster reduction is when a child makes a consonant cluster simpler by dropping one of the consonants in the cluster. This eases articulation while keeping the rest of the sounds intact. For example, in the word blue, the onset cluster /bl/ can be reduced by omitting the /l/, resulting in something like "boo." Similarly, with play, the /pl/ cluster may be simplified by dropping the /l/, producing a form closer to "pay" (the idea being the consonant is left out rather than kept). This pattern is a common early development strategy. It’s different from inserting a vowel to break up a cluster (epenthesis), or from deleting a sound outside a cluster, or from substituting one consonant for another.
