What does candled mean?
Candled is the past tense of the verb 'to candle', a term rooted in the practical craft of inspection by light. Its dominant modern use describes the process of holding an object — most often an egg — against a strong light source to see inside it. Egg graders and poultry farmers have long candled eggs to detect cracks, blood spots, or developing embryos without breaking the shell; today the same technique is performed with electric light boxes, but the word preserves its candlelit origins. Because of this, 'candled' carries a distinctly technical, agricultural flavor and appears chiefly in food-production and quality-control settings. A second, much older sense described anything that glowed or shone like a candle, but this usage has largely fallen out of ordinary speech and now survives only in literary or historical prose. The word is precise, evocative, and a neat reminder of how everyday technology shapes language.
Past tense and past participle of 'candle': to examine an object such as an egg by shining light through it to evaluate its contents or quality.

Almost exclusively used in agricultural and food-industry contexts.
An older sense: to give off light like a candle; to glow or shine faintly.

Now considered literary or obsolete; rarely encountered outside historical texts.
Before ultrasound, farmers had their own way to peek inside an egg — they simply held it up to a candle flame, which is exactly where the word comes from.

Etymology of candled
The word derives from the noun 'candle', which came into Old English as 'candel', likely borrowed from Latin 'candela' via early Germanic contact; the Latin root stems from 'candere', meaning 'to shine or glow white'. The verb 'to candle' arose from the practice of using actual candles as the light source for inspecting eggs and other translucent objects, first recorded around the 17th century. Cognates sharing the Latin root include 'candid', 'incandescent', and 'candle' itself across the Germanic languages.
