The process or condition of chyle formation and circulation in the body, or an abnormal accumulation of chyle in tissues.
From Greek 'chylos' (chyle) + '-osis' (condition/process). The suffix -osis is used in medicine to denote a condition or abnormal state, making this term describe what happens when chyle behaves oddly in the body.
The -osis suffix is so common in medical terms that you've probably heard it in dozens of diseases without realizing they all follow the same Greek naming pattern—from cirrhosis to neurosis, it's the medical world's way of saying 'something's going on with this substance or system.'
