To triumph or win out, or to be widespread and generally accepted in a place or time.
From Old French 'prevaleir,' from Latin 'praevalere' meaning 'to be stronger.' The prefix 'prae-' means 'before/ahead,' and 'valere' means 'to be strong.'
The phrase 'truth will prevail' inspired countless revolutions, but linguistically it's fascinating because 'prevail' originally just meant being physically stronger—our language mirrors how we believe moral strength should triumph like physical strength.
