To undermine or overthrow something established, especially by working secretly from within.
From Latin 'subvertere' where 'sub-' (under/from below) combines with 'vertere' (to turn) meaning 'to turn from underneath' or 'to overthrow.' The word passed through Old French before entering Middle English, carrying the sense of undermining authority or established order.
The beauty of 'subvert' is in its sneaky underground imagery — you're literally turning things from below, like a mole undermining a foundation! Unlike 'invert' which openly flips things, 'subvert' works secretly from underneath to topple what's above.
