Diphthong is a vowel encountercharacterized by the union between a semivowel and a vowel or vice versa. the diphthong can be growing (semivowel + vowel) or decreasing (vowel + semivowel).
In addition to the diphthong, there are two other vowel clusters, that is, the tritongo (semivowel + vowel + semivowel) and the hiatus (vowel + vowel).

What is a diphthong?
Ditongo is a vowel encounter, characterized by the union between a vowel and a semivowel or between a semivowel and a vowel. Therefore, both the word “victory” (“i” is a semivowel, and “a” is a vowel) and the word “kick” (“o” is a vowel, and “i” is a semivowel) have a diphthong.
Diphthong Types
crescent diphthong
It's the meeting of a semivowel with a vowel, in that order. Consequently, they present this type of diphthong, for example, the following words:
- historywas going
- memorywas going
- to beyo
- to beie
- youwow
- limestoneyo
- mingwowbefore
descending diphthong
It's the meeting of a vowel with a semivowel, in that order. Thus, the following words, for example, present this type of diphthong:

Diphthong, tritongo and hiatus
There are three types of vowel encounters:
Diphthong
Triphthong
Gap
As we have seen, the diphthong is the meeting, in the same syllable, of a vowel with a semivowel or vice versa. Examples: rHey, çorsee, sityo.
already the triphthong is the name given to the sequence, in the same syllable, of a semivowel, one vowel and another semivowel, in that order. In this way, it is possible to identify the triphthong in these words: UrugWow, find outwhoa, IGwhatssaghuh.
Lastly, when two vowels meet, we have a hiatus. But beware! According to the rules of syllabic division, there cannot be two vowels in the same syllable. Therefore, this meeting takes place between different syllables: output (sa-í-da), Saara (Sa-a-ra), cruelty (cru-el-da-de), pond (la-go-a) etc.
