What is a "nucleus"?
A nucleus is the central part of a syllable, usually consisting of a vowel sound. It serves as the core around which the rest of the syllable is built, and it is essential for the syllable's structure. For example, in the word "cat," the nucleus is the "a" sound, while in "beat," the nucleus is the "ea" sound. The nucleus is important in phonetics because it contributes to the overall sound and rhythm of speech, playing a key role in how syllables are formed and how words are pronounced in various languages.
