A female captor; a woman who captures or takes someone prisoner.
From captor (one who captures, from Latin capere 'to take') plus the feminine suffix -ess, which creates specifically female forms in English.
Captress is extraordinarily rare in modern English, but historically it was used to describe women warriors, spies, and rebels who captured enemies—it's a word that faded as warfare became more male-dominated in public discourse.
Captress is an archaic feminine suffix form (-ess) parallel to masculine captor. The -ess suffix historically marked women as derivatives of unmarked (male) forms, embedding gender hierarchy into word structure.
Use captor for all genders. The -ess suffix is obsolete in modern professional English.
