The act of consuming, using up, or wearing away something; the state of being consumed or depleted.
From Latin absumptio, from absumere ('to consume'). The suffix -tion is the nominal form, creating a noun from the Latin verb. Related to English 'consumption.'
This word is essentially obsolete in English, but it shows the systematic way Latin created noun forms from verbs—a pattern we still follow in English (consume → consumption). 'Absumption' simply lost out to other Latin-derived words.
