Superlative form of absolute; the most absolute, complete, or unconditional (archaic or emphatic usage).
From absolute plus -est (superlative suffix), following standard English formation despite philosophical debate about whether absolute can have degrees. Found in Renaissance and Enlightenment texts emphasizing extremes.
Medieval thinkers loved absolutest because God was described as the 'absolutest being'—the superlative form made sense in theology where there's literally nothing more absolute than divinity itself.
