    • n filament A tenuous thread of any substance, as glass or mucus; hence, in medicine, a glairy substance sometimes contained in urine, capable of being drawn out into threads or strings.
    • n filament The nearly infusible conductor placed in the globe of an incandescent lamp or glow-lamp and raised to incandescence by the passage of the current. It is usually some form of carbon, although metals with high points of fusion have been used.
    • n filament In geometrical topics, a movable object which at any one instant, or indivisible determination of time, is at every part of a line. During a lapse of time a filament is restricted to being in some surface, which it is said to generate.

And all the precepts that they teach
Were gathered into one
Unbroken line of silver speech,
The shining filament might reach
From earth unto the sun.
