Short Answer 
Polysyllabic words are defined as words with more than one syllable and typically consist of three or more syllables. Understanding the importance of stressed syllables within these words helps improve pronunciation and communication, as highlighted by examples such as “hypothesis” and “vulnerable.”
Step 1: Understanding Polysyllabic Words
A polysyllabic word is defined as a word that has more than one syllable, typically consisting of three or more syllables. The word itself is derived from Greek, where “poly” means “many”, and “syllable” refers to the sound units that make up words. Some common examples include:
- Interdisciplinary
- Opportunity
- Comprehensive
- Independence
Step 2: Importance of Stressed Syllables
Each polysyllabic word has specific syllables that are stressed, which is crucial for correct pronunciation. The stressed syllable carries more emphasis, making it stand out when spoken. For instance, in the word “hypothesis,” the stressed syllable is “POTH.” Properly identifying stressed syllables can help with:
- Improved pronunciation
- Enhanced understanding
- Clearer communication
