    more common and can describe both natural and artificial light; 'lucent' is rarer and more literary

    everyday word for something that shines steadily; less formal than 'lucent'

Antonyms

    producing or reflecting no light

Common Mistakes

The lucent sun was too hot to look at directly.
The bright sun was too hot to look at directly.
'Lucent' describes a pleasant, beautiful glow, not an intensely painful light.

2. describes something that is so pure and free of cloudiness that light passes thr

2.adjectiveC2
Definition

describes something that is so pure and free of cloudiness that light passes through it easily, allowing you to see through it clearly — for example, lucent spring water or the thin, clear ice on a frozen river.

Example

The lucent water of the mountain stream was so clear that Ishaan could count every pebble.

collocation: lucent water

Nellie polished the antique glass until it became perfectly lucent.

predicative use: became lucent

Common collocations
  • lucent water
  • lucent ice
  • lucent glass
  • lucent fabric
Synonyms
  • translucent

    much more common in everyday English; 'lucent' is largely restricted to literary or formal use

  • transparent

    describes something you can see through completely, not just light passing through

  • clear

    the most common word; suitable in all registers and contexts

Antonyms
  • opaque

    completely blocks light from passing through

  • cloudy

    partially blocks vision, as with muddy water or frosted glass

Usage Note

Distinguish from sense 1 (GLOWING WITH LIGHT): sense 2 focuses on light passing THROUGH the object (transparency), whereas sense 1 focuses on light COMING FROM the object (emission or reflection). 'Translucent' is a much more common synonym for this sense.

Common Mistakes

The windows were made of lucent glass that you could not see through.
The windows were made of clear glass that you could see through easily.
'Lucent' describes something that CAN be seen through; a better everyday word is 'clear' or 'transparent.'

3.adjectiveC2
Definition

describes a gentle, warm brightness that is pleasant to look at and not harsh or glaring — for example, the soft light of candles on a dinner table or the first glow of dawn before the sun fully rises.

Example

A lucent glow spread across the horizon just before the sun came up.

collocation: lucent glow

The oil lamp on the desk gave off a lucent light that made the room feel warm and calm.

describing a soft, pleasant light source

Common collocations
  • lucent glow
  • lucent light
  • lucent flame
  • lucent sky
Synonyms
  • soft

    a common everyday word; focuses on the lack of harshness without the literary tone of 'lucent'

  • gentle

    describes light that is easy on the eyes; widely used across all registers

  • mellow

    suggests a warm, rich softness specifically of light or colour

Antonyms
  • harsh

    unpleasantly bright or glaring

  • dazzling

    so bright that it hurts the eyes to look at it

Usage Note

Distinguish from sense 1 (GLOWING WITH LIGHT): sense 3 specifically adds a quality of softness and gentleness that sense 1 does not require. A 'lucent' glow in sense 3 is always described as pleasing and mild, whereas sense 1 can describe any strong glow regardless of whether it feels soft.

Common Mistakes

The headlights of the car were lucent and hurt my eyes.
The headlights of the car were bright and hurt my eyes.
'Lucent' implies a soft, pleasant brightness, not a harsh or painful one.

Synonym discussion

Sense: adjective/1

All four words describe something that gives off or reflects light, but they differ in register and intensity. 'Lucent' is the rarest and most literary of the group — you are most likely to find it in poetry, novels, or formal descriptive writing rather than in everyday conversation. 'Luminous' is more common and can describe anything that shines with its own light (a luminous watch dial, a luminous star) or something that reflects light beautifully (luminous skin). 'Radiant' suggests light that spreads outward with energy, often implying warmth (a radiant smile, radiant sunshine). 'Glowing' is the most casual and widely used — it fits naturally in both spoken and written English (a glowing coal, glowing cheeks after exercise). For everyday situations, choose 'glowing'; for a slightly more formal tone, use 'luminous'; reserve 'lucent' for deliberately poetic or lyrical effects.

Etymology

LatinEnglish

From Latin 'lucēns' (shining), the present participle of 'lūcēre' (to shine), which comes from 'lūx' (light). English borrowed it in the late 1500s, and it has remained a rare, literary word ever since.
