What does glow mean?
Glow names both a soft, steady light and the act of emitting one. Its most familiar literal use describes a lamp, fire, sunset, or other source that radiates warmth without the hard brightness associated with glare. Figuratively, a person or place can glow with health, pleasure, pride, or excitement, and “a glow” can name the warm feeling that remains after such an experience. The verb is usually intransitive, especially in established expressions linking the subject to a feeling or quality. A glow may also be a broad, gentle radiance rather than a sharply defined beam. This flexibility lets the word move easily between physical description and emotional tone: it can make prose feel intimate, hopeful, or cinematic. Compared with “shine,” which is often stronger and more directional, “glow” usually suggests a softer, more enveloping light. As a noun, it is generally used in the singular, although “glows” is also possible when separate sources of light are being referred to.
A soft, steady light or radiance; a warm, contented, or pleased feeling.
"A faint glow from the window suggested that someone was still awake."
Usually singular, especially in the abstract sense of a warm feeling. The plural “glows” is possible but comparatively uncommon.
To emit a soft, steady light; to appear warm, healthy, or pleased; to express pride, happiness, or excitement.
"The old copper kettle glowed as the fire warmed it."
Normally intransitive. Figurative uses often describe a person's expression or manner.
The plural is standard but uncommon; most speakers use the singular for a general or abstract glow.
"Faint glows appeared between the trees."
Glow does what light rarely does: it makes brightness feel warm.

Etymology of glow
The modern English verb dates from the Middle English period and developed from Old English glōwan, meaning “to shine.” The Old English word belonged to a wider Germanic family of shine-related forms, reflected in cognates such as Old Norse glōa and German glühen, and was ultimately connected with an Indo-European root associated with shining. English later developed related forms including “gloaming” and “glower,” while “glare” belongs to a cognate branch of the same broader shine root.
