* Consonant Blends: These involve two or more consonants that are pronounced together, with each sound being distinct. For example, "bl" in "blue," "st" in "street," or "sk" in "skip."
* "-rt" in Words: In words like "heart," "start," or "part," the "r" sound is often silent. The final sound is predominantly the "t" sound.
Therefore, "-rt" doesn't qualify as a consonant blend because the "r" sound is not typically pronounced.
