Step-by-step explanation
The word "respectable" is divided into syllables: re-spec-ta-ble. Syllables are units of sound in speech, and in written language, they are separated by hyphens to indicate their divisions. In this case, the word is broken down into its constituent syllables, making it a division based on pronunciation.
When we break down "respectable" into syllables, we segment it according to how it's spoken. Each syllable contains a vowel sound and can be pronounced independently. This division helps in understanding pronunciation and aids in phonetic analysis.
