the state of having a sufficient or considerable amount of natural light

the glass adds lightness to the room

the lightness of the internal spaces

the quality of being pale in colour

the lightness of my skin

the lightness of her silky hair

the quality of having little weight

you can have the strength of steel with the lightness of aluminium

lack of density, thickness, or richness

the lightness of the material makes them perfect for warm weather

I love the lightness of tempura batter

lack of pressure, force, or heaviness of movement

the lightness of bow on strings

the quality of requiring little mental effort; lack of depth or seriousness

the lightness of the dialogue made it frivolous
