What is a multisyllabic word?
Definition
A multisyllabic word is any word with two or more syllables, such as rabbit, fantastic or celebration.
Most of the words students meet after second grade are multisyllabic, and many reading problems in older grades come down to these words. A student can decode every one-syllable pattern and still freeze at investigation.
The skill is chunking. The student looks for word parts first (prefixes, suffixes), then splits the rest by syllable type, reads each chunk and blends the chunks. With practice it happens quickly and without marking.
Accent matters too. In longer words, one syllable is stressed and the others often weaken to schwa. So the student reads the chunks, then adjusts to the word they know. Teaching that last step keeps students from sounding robotic or giving up.
In a lesson
Give the student unpredictable. They circle un and able, read predict in two chunks, then put it together: un-pre-dict-able. Then they say it naturally, with the stress on dict.

Why does this matter for the record?
Rate multisyllabic decoding by word length. Two-syllable Secure and four-syllable Developing is a common, useful split to record.
