Morphology

tetracaine = caine (semi-transparent) = tetra + caine

The combining form '-caine' signals the class of local anesthetics, but the prefix 'tetra-' is chemically descriptive and not informative to most learners.

Etymology

The word tetracaine starts with tetra- meaning 'four' and ends with -caine, an ending taken from cocaine and used in the names of drugs that 'numb' the body, like procaine. So tetracaine is a kind of local anesthetic, a medicine that makes a small area feel numb.
