The quality or state of being candent; glowing or shining with heat or light; incandescence.
From Latin candentia, derived from candere (to shine, glow) plus -cy (a noun-forming suffix indicating a state or condition).
Candency is an almost poetic scientific term—while we say 'incandescence' in modern physics, candency captures the older sense of something becoming luminous through heat, still used in specialized and literary contexts.
