Examples

Researchers used Ringer solution as a control medium during their physiological experiments on animal tissues.

Morphology

Ringer + solution

While 'solution' transparently indicates a liquid mixture, 'Ringer' is an eponym/proper name with no compositional meaning for learners, so the specific medical sense (an isotonic saline with particular salts used clinically) cannot be derived from the parts. A B1 learner might guess it denotes a particular type of solution but would not predict its composition or clinical use, so the expression is only partially transparent.

Etymology

Ringer solution may be named after the scientist Sydney Ringer, who in the 1800s made a salt mixture that kept animal organs alive outside the body. So today Ringer solution means a clean, germ-free salty fluid used 'to keep tissues alive' and 'to treat dehydration'.
