The process of digesting; digestion (archaic or rare).
From 'digest' plus the noun suffix '-ure' (from Latin -ura). This archaic term, like 'digestment', was largely replaced by the more standard 'digestion' over time.
Medieval and Renaissance English had many '-ure' nouns that we don't use anymore—'digesture,' 'composure,' 'exposure'—showing how language constantly prunes the words it doesn't need as much.
