An archaic or obsolete form referring to the process of absorbing or being absorbed.
From Latin absorbere + -tion (suffix forming nouns of action or result). This is an older variant of absorption, using the -tion suffix directly on the Latin root.
This word is essentially a fossil in English—it's been replaced by 'absorption,' but linguists love finding such archaic variants because they show how language constantly refines itself, often by dropping redundant versions.
