Definition

According to the Liddell-Scott-Jones Lexicon, ἀμαύρωσις (ἡ) is "a dimming, obscuring, blindness." It is a noun derived from the verb ἀμαυρόω, which means "to darken, dim, make invisible." The word is primarily used in medical terminology to describe the weakening or loss of vision, often without apparent damage to the eye, as in cases of glaucoma or cataract.

Beyond its literal, medical sense, ἀμαύρωσις also appears with a metaphorical meaning. It can refer to the obscuring of the intellect, the loss of mental clarity, or the tarnishing of one's reputation and glory. The word implies a process by which something that was bright, clear, or distinct becomes dark, vague, or indistinct.

The significance of the word is underscored by its etymology, as it originates from the adjective ἀμαυρός, meaning "dim, dark, obscure." The presence of the privative or intensive "a-" prefix at the beginning of the word highlights the concept of the absence of light or the intensification of darkness, making ἀμαύρωσις a word that encapsulates the idea of a gradual or complete loss of clarity.

Etymology

ἀμαύρωσις ← ἀμαυρόω ← ἀμαυρός ← ἀ- (privative/intensive) + μαυρός (dark, dim)
The word ἀμαύρωσις derives from the verb ἀμαυρόω, which in turn is formed from the adjective ἀμαυρός. This adjective is composed of the prefix ἀ- (which can be either privative, denoting absence, or intensive, denoting reinforcement) and the root μαυρός, meaning "dark, dim, obscure." The root μαυρός is an Ancient Greek term belonging to the oldest stratum of the language, with no indications of external origin.

From the same root ἀμαυρ- are derived many words that describe the concept of darkening, dimming, or loss of clarity. The verb ἀμαυρόω expresses the action of obscuring, while nouns such as ἀμαύρωμα and ἀμαυρότης describe the state or quality of dimness. Furthermore, compound adjectives like ἀμαυρόφωτος extend the meaning to specific lighting conditions.
