How does nonconcatenative morphology work in Semitic languages?

Nonconcatenative morphology is a form of word formation where roots are modified without stringing morphemes together sequentially. In Semitic languages, words are formed by taking an abstract consonantal root, typically consisting of three consonants, and inserting specific vowel patterns and other markers around them. This system allows a single root to generate a wide family of related nouns, verbs, and adjectives.

What we know

• Nonconcatenative morphology, also known as discontinuous morphology or introflection, modifies the root without stringing morphemes together sequentially. [2]
• Roots of verbs and most nouns in Semitic languages are structured as a sequence of consonants or radicals, often forming triliterals consisting of three letters. [3, 4]
• Words are composed from consonantal roots by filling in vowels and adding non-root consonants or transfixes to match particular morphological categories. [3, 4]
• In Arabic and Hebrew, the root k-t-b meaning write is used to form various words like kitab or katav by inserting different vowels and sometimes additional consonants. [4]
