His most influential work, al-Khasā'is ("The Characteristics"), delves into the origins of the Arabic language, analogical reasoning in grammar, and the philosophical underpinnings of linguistic theory.

Ibn Jinni's contributions profoundly expanded the study of Arabic linguistics to include phonetics and morphophonology, marking a significant advancement in the field.

Ibn Jinni distinguished himself as the inaugural commentator on al-Mutanabbi’s poems, setting a foundational precedent in literary analysis and criticism.

Serving as a scholar in the Buwayhid court, Ibn Jinni's influence extended beyond academia, cementing his role as a key figure in the development of Arabic linguistic thought.

Ibn Jinni himself mentioned his father was named "fāḍilan" (noble) in Greek ("bi-l-rūmiyyah"), referring to the language of the Greek-speaking Byzantines who self-identified as Rhōmaîoi, or Romans.
