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 (but not always) segol.

These words evolved from older Semitic words that ended in a complex coda; indeed, when a suffix (other than an absolute plural) is added to a segolate, the original form (or something similar) reappears (cf. kéleḇ "dog" vs. kalbī "my dog").^{[citation needed]}

Examples:^{[citation needed]}

The ancient forms like *CawC (such as šawr "bull") almost universally evolved to non-segolate CôC (שׁוֹר‎ šôr), though there are exceptions, such as מָוֶת‎ mā́weṯ "death".^{[citation needed]}

Some segolate words' final syllable ends with a patach rather than a segol, due to the influence of guttural consonants (ה‎, ע‎, א‎, ח‎) in the final syllable.^{[citation needed]}

Classical Arabic still preserves forms similar to the reconstructed Ancient Hebrew forms, although significantly simplified.^[1] 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.^{[citation needed]}
