• Avenzoar — The Latinized name of Abu Marwan Abd al-Malik ibn Zuhr (1094–1162), a famous Arab physician, surgeon, and polymath from Islamic Andalusia, widely regarded as one of the greatest clinicians of the Middle Ages. Unlike other contemporary philosophers, he focused almost exclusively on empirical medicine, introducing experimental methods, animal dissection, and drug testing; his main work, 'Kitab al-Taysir', translated into Latin, served for centuries as a reference textbook in European medical universities.
• Averroes — An early or popular Romanian graphic variant for Averroes, the Latinized name of Ibn Rushd (1126–1198), the most famous Arab philosopher, physician, and polymath from Islamic Andalusia; he is renowned in world history for his revolutionary commentaries on Aristotle's works, which laid the foundations of Western radical rationalism (Averroism). The spelling reflects a simplified phonetic adaptation found in some older encyclopedias or literary translations in the Balkan region.
• Averroist — A person who adheres to the principles of Averroism or closely studies the commentaries of Averroes; as an adjective, it describes a work, idea, school of thought, or argumentation closely linked to radical medieval rationalism and Ibn Rushd's Aristotelian interpretations. Representatives of this group often advocated for the autonomy of reason in relation to official theology.
• Averroes — The Latinized name of Ibn Rushd (1126–1198), a famous Arab philosopher, physician, jurist, and polymath born in Córdoba, Islamic Andalusia, widely regarded as one of the most influential thinkers of the Middle Ages. His vast and rigorous commentaries on Aristotle's works preserved and reintroduced Greek philosophical heritage to Western Europe, laying the foundations of scholastic rationalism and profoundly influencing Christian and Jewish theology.
• Averroist — A person who adheres to the principles of Averroism or closely studies the commentaries of Averroes on Aristotelian works; as an adjective, it describes a work, idea, school of thought, or argumentation closely linked to radical medieval rationalism and Ibn Rushd's interpretations. Representatives of this group often advocated for the full autonomy of human reason in relation to official theology within medieval universities.
• Avicebron — The Latinized name of Solomon ibn Gabirol (circa 1021–1058), a famous Jewish poet, theologian, and philosopher from Islamic Andalusia, recognized in the history of medieval culture as a bridge between Oriental Neoplatonism and Western scholasticism. His main work, 'Fons Vitae' (The Source of Life), translated into Latin in the 12th century, exerted a profound influence on Franciscan and Dominican philosophers, promoting the theory of universal hylomorphism, which states that all substances, except God, are composed of matter and form.
• Avicenna — A simplified graphic or phonetic variant used in charts, early medieval treatises, and some old encyclopedias for Avicenna, the Latinized name of Ibn Sina (980–1037), the legendary Persian philosopher, physician, logician, and polymath. Although modern Romanian has stabilized the form Avicenna, this variant reflects a direct adaptation based on early French philological patterns (Avicenne), keeping intact the historical importance of the author of the 'Canon of Medicine'.
