1. A syllable that has two vowels in it, with the stress on the first vowel.
2. A word that consists of two or more syllables joined together without a break.
3. A phrase or clause that contains two or more words that are grammatically related but do not form a single sentence.

5. In prosody, a dissyllable is a metrical foot consisting of two syllables, with the stress on the first syllable.

Examples of dissyllables include:

* "un-der" (a dissyllable because it has two vowels and the stress is on the first vowel)
* "re-laxes" (a dissyllable because it consists of two words joined together without a break)
* "in-de-pen-dent" (a dissyllable because it is a phrase consisting of four words that function as a single unit)
* "the-o-ry" (a dissyllable because it is a noun phrase consisting of three words with the stress on the first word)
* "a-bove" (a dissyllable because it is a metrical foot consisting of two syllables with the stress on the first syllable).
