What does candle mean?
A candle is a cylinder of solid fuel, typically wax, surrounding a wick that is burned to produce light, warmth, or fragrance. For most of human history candles were essential tools of illumination, but today they serve chiefly decorative, ceremonial, and aromatic purposes — on birthday cakes, at religious services, in romantic settings, and as emergency lighting. The word carries warm connotations of intimacy, remembrance, and celebration: we light candles in vigils and memorials as readily as at festive dinners. English preserves the term in many idioms, such as 'to burn the candle at both ends,' meaning to overwork oneself, and the phrase 'can't hold a candle to,' meaning to be markedly inferior. A related technical sense survives in 'candlepower,' an informal measure of brightness now standardized as the SI unit candela. Simple, ancient, and universal, the candle remains one of humanity's most enduring objects.
A cylinder or block of wax with a central wick, burned to provide light.
"He trimmed the wick and relit the candle."
Also used figuratively in idioms about effort and comparison.
A former unit of luminous intensity, now standardized internationally as the candela.
"That bulb produces roughly one hundred candles' worth of brightness."
Regular plural formation. Common in phrases like 'birthday candles' or 'a box of candles.'
"She placed twelve candles around the cake before lighting them."
The word 'candle' comes from the Latin candere, 'to shine white' — the same root as 'candid', because early Roman candles were dipped in pure white wax.

Etymology of candle
Candle derives from Old English candel, borrowed from Latin candela, which itself comes from candere, meaning 'to shine or glow white.' This same Latin root gives us candid, candidate, and incandescent, reflecting the bright whiteness of burning material. The word has been continuous in Germanic languages since antiquity, likely transmitted through early Christian contact with Rome, where candles held liturgical significance.

Usage notes
Candle is a common everyday word with no strong register restrictions. In scientific contexts it appears mainly in older or informal descriptions of brightness; the modern SI unit is the candela. The verb sense — candling eggs to inspect their interior by shining light through them — is largely restricted to agricultural and culinary use.
