What language has no diphthongs?

Some languages do not have diphthongs, except sometimes in rapid speech, or they have a limited number of diphthongs but also numerous vowel sequences that cannot form diphthongs and so appear in hiatus. That is the case of Japanese, Nuosu, Bantu languages like Swahili, and Lakota.

What is the difference between diphthongs and vowel?

While vowels are letters that produce a single sound, diphthongs make two vowel sounds in a single syllable. You would typically break up syllables between two vowel sounds, but diphthongs instead have two sounds without that break.

What type of vowels make up the hiatus words?

A hiatus or diaeresis is a combination of two vowel sounds occurring in different adjacent syllables. There are three kinds of hiatus in Spanish, depending on the open-close vowel sound combination: Open vowel sound + close vowel (and vice versa): frí-o (cold), etí-ope (Ethiopian), or geología (Geology).

What is the mechanism that the language uses to avoid vowel hiatus a sequence of two vowels adjacent to each other )?

To break the cycle of hiatus, elision or deletion has become the major vehicle most languages including Ewe adopt. Elision in general terms is sound lost in speech process. The loss could be a vowel, consonant, syllable which makes way for easy articulation.
