To remove or deprive of strength, energy, or vigor; to weaken someone's ability to act.
From Latin 'de-' (to remove) + 'lumbus' (loin, strength), with '-ate' (verb suffix). The 'lumbus' root relates to the loins, traditionally considered a seat of strength.
In anatomy, the 'lumbar' region (lower back) is where we feel our physical strength, so to 'delumbate' someone is to literally 'take away their loins'—an evocative way to say 'weaken completely'!
