Surface Forms

creatinine singular
creatinines plural

Morphology

creatinine = creatine (semi-transparent) = creatine + ine

Formed from the chemical 'creatine' with the suffix '-ine' indicating a related chemical species, but the specific meaning 'a waste product filtered by kidneys' is a specialized biochemical sense not fully predictable from the base.

Etymology

Creatinine comes from creatine, which comes from the Greek kreas 'meat', because it was first found in meat and is made by muscles. So creatinine is a small waste chemical from muscles that the kidneys must filter, and doctors check it to see how well the kidneys work.
