aglow

Aglo w is an English adjective meaning glowing with warmth or radiance, or figuratively, filled with a strong emotion such as pride or anticipation. It describes both physical light and a state of bright, cheerful feelings. Objects or scenes can be aglow, as in a room aglow with candlelight, or a landscape aglow with sunset colors. The term is often used to convey a gentle, inviting glow rather than sharp brightness.

Usage and nuance: Aglow is typically used with a prepositional phrase to indicate what causes the glow, as in aglow with pride, aglow with excitement, or aglow from the city lights. It is commonly employed in descriptive writing, journalism, and literary prose to evoke atmosphere or mood. The word is usually adjectives in predicative position (The town was aglow) but can appear attributively in more literary styles (an aglow storefront).

Origins and related terms: The word is formed from the prefix a- meaning “in a state of” plus glow, and has been part of English for centuries. It is closely related to other glow-based descriptors such as glowing, radiant, or incandescent, but aglow often carries a softer, more intimate or celebratory connotation.

Notes: Aglow is typically used in plain, non-technical writing. It is not commonly used as a verb. It remains a vivid but somewhat literary choice for describing light, warmth, or heightened emotion.
