Which word provides the best example of consonant cluster reduction intervention?

Consonant cluster reduction intervention focuses on simplifying complex consonant clusters to help with speech clarity and fluency. In the context of the options provided, "stop" represents a word that contains a consonant cluster at the beginning (/st/).

When addressing consonant cluster reduction, a therapist might work with a child to simplify the /st/ sound by removing one consonant, resulting in a pronunciation like "top." This target makes "stop" an effective example of consonant cluster reduction intervention.

The other words present different phonological structures. "Knight" involves a consonant cluster but features a silent letter, which complicates the cluster reduction concept. "Laugh" has a more complex representation overall without a clear consonant cluster in terms of therapeutic focus, while "wish" consists of a single consonant followed by a vowel, lacking a cluster to reduce. Therefore, "stop" is the most suitable example in this context for consonant cluster reduction intervention.
