Segolate
Segolates are words in the Hebrew language whose end is of the form CVCVC, where the penultimate vowel receives syllable stress. Such words are called "segolates" because the final unstressed vowel is typically segol.
These words evolved from older Semitic words that ended in a complex coda; indeed, when a suffix is added to a segolate, the original form reappears.
Examples:
The ancient forms like *CawC almost universally evolved to non-segolate CôC, though there are exceptions, such as mā́weṯ "death".
Some segolate words' final syllable ends with a patach rather than a segol, due to the influence of guttural consonants in the final syllable.
Classical Arabic still preserves forms similar to the reconstructed Ancient Hebrew forms, although significantly simplified. Examples include ʼarḍ "earth", kalb "dog", ʻayn "eye", ṣidq "sincerity".
Some modern dialects insert an epenthetic vowel between the final two consonants, similar to what happened in Hebrew.
