Here's why:
* Syllabic structure: All languages have syllables, but some favor very simple ones. In the example you gave, each syllable would be a single consonant followed by a single vowel (CV).
* Reduplication: Reduplication is the repetition of a syllable or part of a word, which can be used for grammatical or semantic purposes. Languages that use reduplication often have simple syllable structures.
Examples of languages with these characteristics:
* Polynesian languages (like Hawaiian, Samoan, and Maori) often have simple CV syllables and use reduplication extensively.
* Languages of the Niger-Congo family (like Yoruba and Igbo) also have simple syllables and use reduplication.
Important Notes:
* No language is purely "CV": Even languages with simple syllables often have more complex syllables, such as those with multiple consonants or vowels.
* Other factors: A language's sound system is influenced by many factors, including its history, geography, and contact with other languages.
If you have a specific language in mind, it's best to research its phonology directly to learn more about its syllable structure and use of reduplication.
